橡胶楔体与刚性缺口接触大变形分析

, 2000
利用Knowles与Sternberg提出的非线性弹性大变形应变能函数，对橡胶楔体与刚性缺口接触问题进行了大变形渐近分析，推导了楔体尖端场的渐近方程。得到楔体尖端附近的应力应变场及应力的奇异性指数与橡胶楔体角度、刚性缺口角度及材料常数有关的表达式；楔尖附近同一半径上应力分量为常数。同时，利用非线性有限元理论编制了大变形有限元程序，考虑楔体尖端与缺口接触边界条件 ...

铰接圆柱体在二色波中的二阶低频力

, 1995
考虑了铰接圆柱体的响应,给出了二色波中铰接在海底的圆柱体的二阶低频力。在未求出二阶速度势的情况下,利用其定解条件,给出了二阶速度势的影响,给出了二阶低频力的解析表达式。二阶低频力主要由一阶速度势决定 ...
