1、rectagular structure : 5*5 (cm2); E=210Gpa; 泊松比0.3;
2、Q=-10MN/m~10MN/m ( 线性变换如图);
3、the rectangular structure is fixed at the top and subject to a negative initial gap of 0.1um at the bottom which is regarded as the contact surface;(the object which under the rectagular structure is fixed)
4、摩擦系数u=0.4,磨损系数k=1.0e-11;
5、each cycle is divided into 80 time increments.
6、the contact surface is discretized by 30 contact elements.
欢迎出题,共同提高
求出垂直应力(normal contact pressure)加一分。做出第二问求出磨损间隙加2分
