On these bases, by applying the contact searching algorithm combined with Lagrange multiplier method for friction and contact, finite element analysis is carried out for the numerical simulation of super-plastic forming processes.

• 在此基础上,利用接触的搜索算法和拉氏乘子法对板材成形过程中的接触和摩擦问题进行了处理,实现了有限元法对金属板材超塑性成形过程的数值模拟。
