The results show that, for the elasto-plastic contact of tip-substrate approach and separation process, the material plastic yielding in the atomic level is still governed by the von Mises criterion. For the adhesion of flat-ended wedges, continuum mechanics can be still applied down to a few lattice constants within the contact region, and give reasonable results, apart from the discrepancies near the contact edges. Moreover, adhesion hysteresis occurs during unloading due to the atomic steps, where the unloading curve does not coincide with the loading one. This in turn supports the presumption proposed by Pollock for the adhesion of stepped spheres.

本文首先对针尖—基体模型的弹塑性接触机理进行了深入研究，指出在原子水平上材料的塑性屈服仍由Von Mises准则控制；对平底锥冲头粘着接触的模拟表明，除了在接触区边缘附近有一定差别外，接触力学方法在接触区内几个晶格常数范围内仍能给出令人满意的结果；由于原子台阶效应，加载与卸载曲线不重合，出现粘着滞后，证实了Pollock关于具有纳米阶梯结构的球体粘着滞后现象的推测。

A cusp catastrophe model is presented to describe the behavior of sliding along one deep incompetent structural plane of a gravity dam foundation, and the sufficient conditions leading to instability are discussed. It is found that the instability of sliding relies mainly on the stiffness ratio k, the homogeneity index of the medium m and the geometry-mechanic parameter ξ and that the reliability of the traditional limit analysis method is deficient.

通过建立的模型分析，发现坝基滑动失稳主要取决于软弱面上复杂弹脆性介质和应变软化介质在应变软化拐点处的刚度比k、材料的均匀性指标m及几何－力学参数ξ；并给出了发生突变失稳的充分力学判据，指出传统的刚体极限平衡分析法存在一定的缺陷。

Gargoyles carry away excess water via pipes running through their mouths; grotesques deflect rainwater by bouncing it off the top of their heads, noses or other projecting parts, and away from the stone walls.

滴水嘴通过穿过它们嘴巴的管道，将超量的水排出；滴水怪兽则是通过用自己的头顶、鼻子或其它突出部分将雨水弹开以偏转雨水，让雨水远离石墙。

Finally we build a set of mechanical model which is a series of a nonlinear spring and a nonlinear vogit model to simulate the viscoelastic property of heel pad effectively.

最后本研究建立一组非线性弹簧与一组非线性vogit模型串联的数学模型可有效模拟出软组织的黏弹特性。

There are many problems in the carling forming and unloading processes such as expand and shrink of U section wall, the torsion of U section and the warp of carling head.

针对纵梁冲压成形及卸载后发生的U型截面侧壁的外扩、内缩、扭转以及纵向端头翘曲等问题，首先分析了纵梁的成形及回弹变形机理，利用仿真分析软件KMAS进行了数值模拟并采用半解析、半实验方法研究了纵梁底面翘曲，找出模具结构的最佳方案。

There are many problems in the carling forming and unloading processes such as expand and shrink of U section wall, the torsion of U section and the warp of carling head. These problems are concerned by the carling factories and do not solved for a long time. The mechanism of the carling forming and spring back is analyzed. The carling forming and spring back processes are simulated by KMAS software. The warp of carling underside is researched by half analytic and half experiment method and the best scheme is found by this method.
