摘要
选择新的三类变量建立了放松单元间连续性条件的用于非线性有限元分析的泛函，并由此建立了基于不协调模式的非线性广义杂交元方法。
Based on a rational choice of the admissible functious,which are the displace-ments,the displacement-gradients and the first Piola st resses,as the independent variables,the new variational principles with relaxed inte relement continuity requirements have beendeveloped for nonlinear finite element method,and the generalized hybrid methods for non-linear analysis by use of the nonconforming models are established.
