A depth-sensing indentation system was used to measure the residual stress in a stainless steel plate implanted by Fe2+ ions with an energy of 3 MeV at a dose of 3 x 10(16) cm(-2). Unlike other measurement methods, such as substrate curvature and X-ray diffraction techniques, depth-sensing indentation provides an accurate measurement of local residual surface stresses in the thin ion-implanted lay...<br/><br/>Q Wang, K Ozaki, H Ishikawa, S Nakano, H Ogiso (2006) <i>NUCLEAR INSTRUMENTS & METHODS IN PHYSICS RESEARCH SECTION B-BEAM INTERACTIONS WITH MATERIALS AND ATOMS</i> <i></i> <i></i> 242: 1-2 88-92<br/>

In this paper, the strength of the singular stress field near the ends of the CNTs in composites was analyzed to clarify the effects of the CNT length on stress filed in the CNT reinforced composites when studying the fracture toughness. The singular stress field was separated into two types of singularities, symmetric and skew-symmetric, near the ends of CNTs according to the deformation and load...<br/><br/>Q Wang, X F Sun, K Ozaki (2006) <i>Fracture and Damage Mechanics V, Pts 1 and 2</i> <i></i> <i></i> 324-325: 855-858<br/>

Several different species of ions, An, Fe, Ag, Ti and Si, were implanted into austenite stainless steel sheets at an energy of 3 MeV, respectively. The martensite transformation induced with the ion implantation was investigated with transmission electron microscopy equipped with an energy dispersive X-ray spectrometer. The residual stresses induced with ion implantation were evaluated by the curv...<br/><br/>Q Wang, K Ozaki, H Ishikawa, S Nakano, H Ogiso (2006) <i>SURFACE REVIEW AND LETTERS</i> <i></i> <i></i> 13: 2-3 329-334<br/>

In this work, we investigated the influences of residual stress on the load shifts, irreversible work from load vs. depth curves. It is found that there are linear relationships between the level of surface residual stress, the load shifts, and the variation of irreversible work for Ni, Ti, TiFe and A316L studied in this work. From these effects of residual stresses on load versus depth curves, de...<br/><br/>Q Wang, K Ozaki (2006) <i>Fracture and Damage Mechanics V, Pts 1 and 2</i> <i></i> <i></i> 324-325: 89-92<br/>

Based on the effects of residual surface stress on the unloading curves of indentation load-depth responses, an experimental scheme for determination of the residual stress by depthsensing indentation is proposed. From the point that the elastic unloading portion of the load-depth curves can be expected to be unaffected by the residual stresses, the formula for evaluating surface stress by indenta...<br/><br/>Q Wang, K Ozaki (2005) <i>Fundamentals of Nanoindentation and Nanotribology III</i> <i></i> <i></i> 841: 33-38<br/>

Residual stress in ion-implanted stainless-steel sheet and the effects of ion species and implantation dose on the residual stress were investigated by using curvature technique based on the Stoney equation. Six species of ions of An, Ag, Fe, Ni, Ti and Si were implanted into the stainless steel sheet with an energy of 3 MeV at the dose of 1.0 x 10(16) to 10(17) ions/cm(2).

Gold nanoparticles can be used as a catalyst when deposited on a material surface. Adhesion to the support surface is a problem, however, and thus prevents the particles from being an effective catalyst. Adhesion in specified microscale regions is needed in recently developed micro total analysis systems (mu-TAS) and other microchemical systems such as "lab on a chip". Both types of systems have c...<br/><br/>S Nakano, M Ishizuka, Q Wang, H Ogiso (2004) <i>SURFACE & COATINGS TECHNOLOGY</i> <i></i> <i></i> 187: 2-3 167-171<br/>

Ion implantation causes changes in mechanical properties such as hardness and fracture toughness on the ion-implanted surface. The purpose of this study is to experimentally investigate the effects of substrate temperature during ion implantation on the hardness and fracture toughness of an ion-implanted silicon wafer.

Investigations were carried out on the relation between the martensite transformation and the stress induced by 3 MeV ion implantation in an austenite stainless steel (SS) sheet. Gold ions were implanted into the austenite SS sheet and the implantation dose was varied between 1 x 10(16)/cm(2) and 3 x 10(16)/cm(2).

In short fiber reinforced composite it is known that the singular stress at the end of fibers causes crack initiation, propagation, and final,failure. The singular stress field is controlled by the generalized stress intensity factors defined at the end of the inclusion.

In this paper a singular integral equation method is applied to calculate the distribution of stress intensity factor along the crack front of a 3D rectangular crack. The stress field induced by a body force doublet in an infinite body is used as the fundamental solution. Then, the problem is formulated as an integral equation with a singularity of the form of r(-3).

Investigated is the push-in test used to determine the interfacial strength of fiber-reinforced composites via the method of singular integral equation. Singularity analysis shows that stresses near the end for an intact interface have a power singularity, and the singularity index is only dependent on the material constants of the fiber and the matrix. In order to describe the interfacial strengt...<br/><br/>Q Wang, X Ji, Y G Wang (1998) <i>SCIENCE IN CHINA SERIES E-TECHNOLOGICAL SCIENCES</i> <i></i> <i></i> 41: 5 471-481<br/>
