The singular boundary method for unilateral contact problems
Journal of the Brazilian Society of Mechanical Sciences and Engineering（2022）
摘要
The singular boundary method (SBM) is developed and applied for unilateral contact problems by means of the implicit projection iterative method (IPIM). The IPIM removes the nonlinearity of unilateral contact problems. The SBM solves linear elastic problems iteratively. Numerical studies illustrate the accuracy and convergence of the proposed algorithm.
