【摘要】 接触问题是一个极其复杂的非线性问题，单独使用数值方法或实验方法求解应力都有一定的困难．有限元计算与平面光弹性实验相结合的混合法是对接触问题进行应力分析简单而有效的途径．更多还原

【Abstract】 Contact problem is a complex and nonlinear one. A number of difficulties will appear when only numerical or experimental method is adopted to solve it. The mixed method, which combining the finite element method with plane photo elasticity experiment method, is a simple and effect method for solving contact problem.更多还原
