PI计划进行一些重点实验和理论建模 其目的是根据一种模式制定宪法, 裂纹愈合和亚临界裂纹增长。 他已经开发 一个初步的理论模型,这些过程作为 它的基本基础,并发现这个模型适合 实验数据优于现有模型。 他还 在对蛇纹石的实验中发现,有明确的证据表明, 在摩擦滑动过程中同时进行两个过程, 其相对重要性取决于滑动速度。
英文摘要
The PI plans some focused experiments and theoretical modeling that are aimed at attaining a constitutive law based upon a model of crack healing and subcritical crack growth. He has developed a preliminary theoretical model, with these processes as the underlying basis for it and has found that this model fits the experimental data better than the existing models. He has also found in experiments on serpentine that there is clear evidence of two processes operating simultaneously during frictional sliding, with their relative importance depending upon sliding velocity.
