摘要
利用Knowles与Sternberg给出的非线性弹性大变形应变能函数,对橡胶材料无限长圆筒受均匀内压问题进行了大变形分析,推导了求解方程并作了数值计算,井利用有限元进行验证,得到与解析解一致的结论。当圆筒外径为无穷大时,便得到无限介质中的筒腔问题的解。
This paper analyses the uniform internal pressure on rubber limitless cylinder from the aspect of large deformation, derives the equation and calculates the numerical value. After verifying the equation with finite unit, a conclusion is drawn in accordance with analytical solution. When the outside diameter of cylinder is infinite, the solution of cylinder problem will be made in infinite medium.
