	Abstract:In this paper, we proposed a non-destructive measurement method combined with digital image correlation and acoustic emission techniques to in-situ monitor the interface failure and internal damage of brittle coating/ductile substrate systems under different size scales. We established a good correspondence relationship between digital image correlation and acoustic emission results to judge coating failure. The method was utilized to successfully determine the fracture toughness of thermal barrier coating systems during bending tests.

	Abstract:This paper investigates deformation configuration of small bundle of single-walled carbon nanotubes (SWCNTs). The continuum hollow beam model is adopted. If suspend freely, a pair of CNTs will not remain parallel but twist with each other forming a helix structure. This result is comparable to that analyzed from Buehler's simulation [12]. We also investigate situation of 3 or 7 CNTs that form a bundle. If two CNTs are constrained on a plain and their lengths do not coincide, there will be a bow structure. These effects will be more prominent for more slender tubes, and these phenomena will influence application and mechanical property of CNT.

	3. Molecular Gun Composed of Carbon Nanotube

	Abstract:using molecular simulation, this paper predicts that by bending one end of the outer carbon nanotube (CNT) of a double-wall CNT(DWCNT), the inner CNT could possibly be shot out with a speed of several 100m/s, and a kinetic energy of several eV from either left or the right end of the outer CNT, depending on the length of inner CNT. Analysis in this paper suggests that the outer CNT is a supplier of the CNT bullet's kinetic energy and the bullet can be shot out only if the outer CNT buckles while the inner CNT does not. Noticeably, such molecular gun could be practical in experiment environment since the bending of a CNT could be obtained by applying external electrical field.

	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:Bolt support has been the main support form of the mine roadway in the underground endineering because of its obvious technical and economical superiority.Th theory of bloting is maturing with the practice of bolting technology continuously enriched.For this study,we built a mechanical modle for bolting,which represented the effect of a bolt on the surrounding rock in roadway. Simultaneously,we use the displacement method in elastical to deduce the elastic solution of forcing at point in the interioe of a semi-infinite solid. And we analyzed factors affecting the radical compression of the bolt on the surrounding rock. The results indicate that 1) the maximum radical compression stress declines first and then rises with the increase in depth from the surface of the anchorage surrounding rock and 2) the size of the radical compression area is mainly determined by the length of the bolt.

	6. Achieving desired thermomechanical fields in functionally graded hollow cylinders by material tailoring

	Abstract:A technique of material tailoring to achieve desired thermomechanical fields in hollow cylinders composed of functionally graded materials (FGMs) is presented in this paper. First, the desirable stress distribution and temperature field are prescribed. And then the required variations of the Young's modulus, the Poisson's ratio and the thermal expansion coefficient with the radius to achieve the corresponding state of stress and temperature distribution within FGMs cylinders are found. Different kinds of the required variations of the material constants with the radius to fulfill the same purpose are given for FGMs cylinders. The multi-optional variations of the material constants to achieve the same desired thermomechanical field presented here may be interesting and helpful to the design of the inhomogeneous material.

	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.

	8. Requirements of the nanoscale twin boundaries serving as dislocation sources

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

	Abstract:Nanoscale twin boundaries with initial defects are found to be easy dislocation sources in experiments. Here, deformation of nano-twinned single crystals is performed by using atomistic simulations. It is revealed that perfect TBs potentially are not dislocation sources. Another observation is that plastic deformation under uniaxial tensile loading can be dominated by TB migration in samples with inclined TB orientation. Twin planes with disconnections induced by dislocation-TB interactions are obtained during nanoindentation. Under further plastic deformation, it is observed that nucleation of dislocations occur at the disconnections where coherency of TBs has been destroyed.

	9. Understanding the enhancement of coating's thermal cracking resistance by multiple segmentation cracks
	Chen Xuejun,Chen Guangnan
	Mechanics 10 January 2011
	Show/Hide Abstract \| Cite this paper︱Full-text: PDF (0 B)

	Abstract:The cracking of coating is a common phenomenon for a coated medium subjected to thermal transients and usually causes subsequent delamination of coating. Experimental results showed the thermal cracking resistance of a coating could be greatly improved by introducing multiple segmentation cracks but the underlying mechanism remains to be revealed. In this paper, the thermally induced cracking behavior of a segmented coating on the outer surface of a hollow cylinder has been investigated. The driving force for the propagation of multiple segmentation cracks, represented by the Thermal Stress Intensity Factor (TSIF), was determined by combination of the principle of superposition and the finite element method. The maximum TSIF has been shown to occur neither at the beginning nor at the steady state of thermal transients, but at an intermediate instant. It has also been found that, as the spacing between multiple segmentation cracks decreases, the magnitude of TSIF first plateaus, and then decreases sharply. This quantitative mechanistic result rationalizes the experimental observations that a segmented coating can exhibit much higher thermal cracking resistance than an intact counterpart, if only the density of multiple segmentation cracks is high enough. Some other parameters affecting TSIF, such as segmentation crack depth and convection severity, were also discussed.

	Abstract:In this paper, the thermally driven edge-cracking behavior of a coating-substrate system has been investigated. The transient thermal stress field has been derived in a closed form for the corresponding un-cracked counterpart medium. By applying the equal thermal stresses but with opposite sign on the crack surface to be the only external load, the thermal stress intensity factors (TSIFs) at the crack tip were then obtained. The finite element method was utilized to implement the calculation. Based on dimensional analysis, the main dimensionless parameters affecting TSIFs were identified and the dependence of TSIFs on these parameters was illustrated such as dimensionless time, crack depth, thermal constants as well as mechanical constants. These results may provide some useful references for designing coating-substrate system under rapidly changing thermal environments.
