用互易定理导出了弹性静力学问题的边界积分方程,并由弹性接触的协调条件和力平衡条件获得了接触的补充方程,从而将弹性接触问题化为一组线性代数方程求解。接触区的计算采用了逐步逼近法。计算结果与理论值的对照说明这种方法数方法可给出满意的计算结果。
Boundary integral equations of elasticity statics problems are derived by the reciprocity theorem. The complementary equations of contact are obtained from the coordination conditions and equilibrium conditions of elastic contact, so that the elastic contact problem can be solved by a set of linear algebraic equations. Contact area calculation using the gradual approach. Comparing the calculated result with the theoretical value shows that this method can give satisfactory results.
