	Show/Hide Abstract \| Cite this paper︱Full-text: PDF (0 B)

	Abstract:Three-dimensional computational modeling and theory predicts new feature of two-phase coexistence, i.e. appearance of a tetragonal-orthorhombic mixed state, other than conventional tetragonal-rhombohedral coexistence of decomposing Pb(Zr1-xTix)O3 (PZT) ferroelectric solid solutions near the morphotropic phase boundary (MPB). It shows that the new phase-coexistence state is formed through the phase with weak polar anisotropy loosening the rotational stability of polarization, driven by significantly decreasing the energy due to the deformation and polarization incompatibility between two phases.

	Abstract:A fast, robust and accurate digital image correlation (DIC) method, which uses an efficient inverse compositional matching Gauss-Newton (IC-GN) algorithm, was recently proposed for full-field deformation measurement. As an iterative local optimization algorithm, IC-GN algorithm iteratively solves for the incremental warp assumed on the reference subset until the preset convergence criteria are satisfied. In the literature, different convergence criteria have been set for iterative optimization algorithms. However, on the one hand, stringent convergence criteria lead to increased number of iterations and lessen the computational efficiency. On the other hand, too loose convergence conditions enhance the computational efficiency but may decrease the registration accuracy. Understanding the impact of prescribed convergence criteria on DIC measurement and how to choose proper convergence criteria are therefore fundamental problems in realizing high-efficiency yet high-accuracy DIC analysis. In this paper, the convergence characteristics of IC-GN algorithm are investigated using real experimental images. The effect of various convergence criteria on the efficiency and accuracy of IC-GN algorithm are carefully examined. Recommendations are given to select proper convergence criteria for more efficient implement of IC-GN algorithm.

	Show/Hide Abstract \| Cite this paper︱Full-text: PDF (0 B)

	Abstract:Critical buckling problem of complex structures with uncertain initial geometric imperfection was studied based on the non-probabilistic convex methods. By virtue of the Taylor series expansion, interval analysis and convex models were proposed to predict the worst critical buckling load and the weakest shape of the initial geometric imperfection for complex structures, which may overcome the limitation of the analytical or series solutions of critical buckling load that is viable only for simple structures. The non-probabilistic convex methods and probabilistic method were compared critically. Composite stiffened plate and cylindrical shell were used to illustrate the feasibility and validity of the proposed methods.

	4. Buckling Solutions of FGM Timoshenko Beams in Terms of Those of the Homogenous Euler-Bernoulli Beams

	Abstract:Analytical relationships between the solutions of buckling of functionally graded material (FGM) Timoshenko beams and those of the homogenous Euler-Bernoulli beams subjected to axial compressive load were investigated for different boundary conditions. Based on the first order shear deformation theory, governing equation of buckling of FGM beams with the material properties changing continuously arbitrarily in the thickness direction were derived only in terms of the deflection, which has the same form as that of the homogenous Euler-Bernoulli beams. By solving the governing equation with specific boundary conditions, an analytical relationship between the critical buckling loads of the FGM Timoshenko beams and those of the corresponding Euler-Bernoulli beams were obtained which is valid for the clamped-clamped(C-C), simply supported-simply supported (S-S) and clamped-free(C-F) end constraints. Unfortunately, the above mentioned relationship is not valid for the beams with clamped-simply supported (C-S) ends. However, a simple eigenvalue equation is presented to find the critical buckling load for a C-S FGM Timoshenko beam. Consequently, buckling loads of FGM Timoshenko beams with C-C, S-S and C-F ends can be simplified as calculations of two coefficients determined by the material gradients and the geometry of the FGM beams when the critical buckling load parameters are known.)

	Abstract:The influence of microstructures e.g. microcracks on the near-tip stress-electric field for an impermeable macrocrack in piezoelectric materials was studied using the existing pseudo-traction methods. The macrocrack could be modeled as impermeable one for its surrounding insulation environment whilst the microcracks could be modeled as permeable slit cracks due to poling or other sources without the crack surface opening effect. The conservation of the J-integral holds true for the configuration with a permeable microcrack near the tip of an impermeable macrocrack. Finally, the influence of the permeable microcrack on the macrocrack tip could be modeled as the stress intensity factor (SIF), electric displacement intensity factor (EDIF), and mechanical strain energy release rate (MSERR) in comparison with the previous work. It is found that the divergences between the present permeable microcrack model and the previous study are remarkable under combined electric-mechanical loading. The disturbance of the permeable microcracks on the near-tip stress-electric field due to the positive electric field loading is always much smaller than that given in the previous impermeable model.

	Abstract:An acoustic emission technique was used to monitor the cracking behavior and fracture process of thermal barrier coatings subjected to tensile loading. Acoustic emission signals were extracted and preformed by fast Fourier transform, and their corresponding characteristic frequency spectrums and dominant bands were obtained to reveal fracture modes. Three different characteristic frequency bands were confirmed, corresponding to substrate deformation, surface vertical crack and interface delamination, with the aid of scanning electronic microscopy observations. A map of the tensile failure mechanism of air plasma-sprayed thermal barrier coatings was established. Using experimental data, the fracture strength and interface shear strength were estimated as 45.73 ± 3.92 MPa and 20.51 ± 1.74 MPa, respectively, which are well agreement with available results..

	7. Optimal design of functionally graded hollow cylinders based on the micromechanical model

	Show/Hide Abstract \| Cite this paper︱Full-text: PDF (0 B)

	Abstract:Optimal design of hollow cylinders composed of linear elastic functionally graded materials (FGMs) is carried out in this paper. The volume fractions of two phases of FGMs are assumed to vary only with the radius and the effective material properties are estimated by using the Mori-Tanaka scheme. For a FGMs cylinder under non-axisymmetric loads the variation of the volume fraction of the two phases is determined for the hoop stress to be constant through the thickness but have the same periodicity in the circumferential direction as the applied load. It is found that the optimal radial distribution of the volume fractions of the phases depends on the circumferential wave number of the applied loads. The results of optimal design for hollow cylinders under asymmetric loads should be helpful for structural engineers.

	Abstract:How to quantificationally detect the damage of rocks is a key problem in damage mechanics for rocks, and it determined whether the damage theory of rocks could be brought into action in rock engineering. Detection techniques of rock damage were summarized and grouped into structural analysis approaches and feature measurement approaches, which include SEM analysis, CT detection, stress-strain measurement, wave detection, acoustic emission monitoring, infrared radiation detection, etc. All kinds of damage variables resulted from different methods are equipollent in thermodynamics, and they are an internal variable to characterize damage state. The distinguish of each kind of damage variable is that different formations of state equations and dynamic equations would be derived from different variables. It was suggested that the favorable rock damage variables should be selected according to the thermodynamics principle and those convenient to detect and easy to analysis should be adopted preferably.

	Abstract:The adhesive contact problem of a functionally graded coated half-space indented by a rigid spherical punch is considered. The whole contact region is assumed stick with the interfacial friction sufficiently large to prevent any slip from taking place between the indenter and the half space. The linear multi-layered model is used to model the functional graded coating with arbitrarily varying shear modulus and constant Poisson’s ratio under axisymmetric loads. By using the transfer matrix method and Hankel integral transform technique, the problem is reduced to a set of Cauchy singular integral equations. An iterative method is developed to solve singular integral equations numerically. Normal contact pressure and tangential tractions in the whole contact region are calculated. It is found that appropriate gradual variation of the shear modulus can significantly alter the contact traction.

	Show/Hide Abstract \| Cite this paper︱Full-text: PDF (0 B)

	Abstract:Soil-structure interaction emanating from seismic stationary random excitations is studied using the pseudo excitation method in combination with the precise integration method. The soil considered is a viscoelastic, transversely isotropic and layered half space and the structure which it supports is modelled by the finite element method. The excitation sources are random field ones that are stationary in the time domain and are located in the soil. The pseudo excitation method is used to transform this stationary random soil-structure interaction problem into a series of deterministic harmonic response analyses and the precise integration method is used to integrate the ordinary differential equations in the frequency-wavenumber domain. The power spectral densities of the soil-structure interaction responses caused by the stationary random excitations are investigated.
