| Abstract: | Based on S R decomposition theorem of finite deformation, the power form of energy principle by taking external body moment into account was presented. The incremental virtual power principle and the corresponding basic equations of finite element were deduced, providing a theoretical basis for solving engineering practical problems of large deformation and large rotation. |
