The elasto-plastic finite element analyses for an interface crack in dissimilar material, based on the crack energy density (CED) concept, are investigated in mode I loading condition. It is confirmed that the values of CED almost remain stable when the notch radius rho is sufficiently small, both in elastic and elasto-plastic case. Numerical results for both elastic and elasto-plastic cases show that under the mode I loading condition, when the crack propagates to the more stiff material with a small angle, the total CED will become larger than that along the interface. If the clack heads into the more compliant material, the CED will become less than that along the interface.

1 Results Helix induction to polymer chains is an active area of research these days. In most cases,optically-active units are attached to the polymers to induce helical conformation. Scheme 1Since the properties of σ-conjugated polymers like polysilanes are dependent on the conformation of the chain,it is particularly interesting to induce helix to oligo-and polysilanes. We have been working on the helix induction by host-guest complexation with sugar derivatives such as cyclodextrine and *** l...

CZ-Si and FZ-Si single crystal specimens were irradiated by electron beam with energy of 1MV in HVEM at temperatures between 298K and 773K. It was found that irradiated defects were easier to produce in Si single crystal containing oxygen than in Si containing hydrogen. The defects had a larger density and shorter incubation time in Si containing oxygen. The bar-like defects, stacking faults and loops were along 110 direction. Bar-like defects and stacking faults were Burgers vector 116 direction type and the stacking faults were on the (113) plane.

最近高功率车用发动机的紧凑和轻型结构的趋势已迫使对轴瓦的疲劳强度、抗咬合性和顺应性提出了更高的要求。为了满足这些要求,作者分析了铝-硅-锡多层轴瓦的每层性能,并研究了其对轴瓦性能的影响。根据研究结果,对轴承合金和中间粘接层作了改进。因而,这种新改进的轴瓦能提供比传统轴瓦更高的疲劳强度。这样就有可能使它成为当前用于苛刻条件下的发动机的一种轴瓦。

In recent years, a great interest is focused on molecular recognition using weak intermolecularinteractions. Among the weak interactions, hydrogen bond interaction betweencomplementary bases plays decisive roles in biological recognition systems. There exist greatefforts to use hydrogen bond interactions for biosensors. In earlier studies, it was assumed thatA-T and G-C types hydrogen bond pairs found in biological systems are formed also in theartificial molecular recognition systems. Nevertheless, very limited studies have confirmed
