	Abstract:Zanaboni Theory is mathematically analyzed in this paper. The conclusion is that Zanaboni Theorem is invalid and not a proof of Saint-Venant's Principle; Discrete Zanaboni Theorem and Zanaboni's energy decay are inconsistent with Saint-Venant's decay; the inconsistency, discussed here, between Zanaboni Theory and Saint-Venant's Principle provides more proofs that Saint-Venant's Principle is not generally true.

	Abstract:Since the crack tip displacement field influences the crack paths under both fatigue and fracture conditions strongly, it is very important to develop a test method with high accuracy to measure this deformation parameter. Single-element extended digital image correlation (X-DIC) using the enrichment function to describe the crack tip singularity, which could measure the discontinuous deformation directly. Simulated images are used to verify the performance of single-element X-DIC, the measured crack tip displacement field is in accordance with the given value. Displacement fields of the compact tension specimen under pure mode I loading condition was measured. The influence to the measurement accuracy caused by the crack width，subset size and subset location was discussed. All results in this paper show that single-element X-DIC could be used to measure the crack tip displacement field with high accuracy.

	Abstract:This paper is concerned with the finite fatigue lives of high strength steel SUS 630 H900 taking various defects under high cycle loading in two dimensions (2D) and three dimensions (3D). SUS 630 H900 steel has the extensive applications with specific fatigue features. The related defects refer to long cracks/notches as well as small cracks/notches. The small cracks/notches generally give rise to the size effect on material fatigue strengths and lives. In order to address the size effect, the characteristic fatigue length concept, accounting for the minimum representative size of polycrystalline material under cyclic loadings, is selected to correlate the fatigue lives with the average stress amplitude within the length. In this concept, the characteristic fatigue length is considered as the material intrinsic property and does not vary with the number of cycles to failure. Based on the length, The finite fatigue lives of SUS 630 H900 with various defects are predicted and partially compared with the experimental results. Through the comparison it is found that, the predicted values agree with the experimental results well.

	Abstract:The creep, ratcheting behaviour and fatigue failure, as well as their interaction were investigated by uniaxial cyclic stressing tests for SS304 stainless steel at room temperature, 100oC and 300oC. The effects of mean stress, stress amplitude, stress rate and the peak stress holds on the ratcheting strain and final failure life were discussed. Simultaneously, the variations of responded strain amplitude with the number of cycles were illustrated to discuss the interaction of creep, ratcheting behaviour and fatigue failure. The experimental results show that the creep and ratcheting behaviour for SS304 stainless steel at different temperatures are different. The fatigue life of the material at room and high temperatures all depend greatly on mean stress, stress amplitude, stress rate and the peak stress holds of uniaxial cyclic stressing. And the material show different kind of failure modes: ratcheting failure due to large ratcheting strain and fatigue failure due to low-cycle fatigue with nearly constant responded strain amplitude.

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

	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.

	6. 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.

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

	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.

	8. 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:With the number of social communities grows, social community recommendation has gradually become a critical technique for users to efficiently find their favorite communities. Currently a variety of recommendation techniques have been developed, such as content-based method, collaborative filtering, etc. There methods either easily overfit the data due to the limitation of observations or suffer the heavy computational cost. Besides, they don‘t consider the relationships between users and communities, and cannot handle incoming users. In this paper, we propose a soft-constraint based online LDA (SO-LDA) method. We use the number of user‘s posts within each community as soft-constraint to estimate the latent topics across the communities by an online LDA algorithm, in which an incremental method is adopted to facilitate model updating when incomes a new user. Experiment on the well-known MySpace community data shows that the proposed method takes much less time and outperforms the state-of-the-art community recommendation methods.

	10. Fretting Contact of a Functionally Graded Coating with Exponential Variation of Material Properties

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

	Abstract:This paper is concerned with the fretting problem of a functionally graded coated half-space indented by a rigid sphere under a normal load and a cyclic torque. The shear modulus of the graded coating is assumed to be an exponential function and the Poisson’s ratio is constant. By using Hankel integral transform technique, the contact problem is reduced to a Cauchy singular integral equation. The contact pressures are calculated by solving the equations numerically. The results show that the stick region and angel of rigid rotation depend on the gradient of the functionally graded coating as well as the torque couple. The results also show that the appropriate gradual variation of the shear modulus can significantly alter the contact traction. This may modify the contact damage.
