抄録
A modified formulation of floating stress-point integration with the updated Lagrangian procedure for large deformation analysis is presented. The modified formulation introduces an incremental internal force to the equilibrium equation instead of the virtual external force introduced in the previous formulation. With this modification, the temporal continuity of the mechanical equilibrium can be kept without introducing the virtual external force, and thus the accumulating error due to time advancing becomes small compared to our previous formulation. Several examples of large deformation analysis including large deformation patch tests are also presented to show the validity and accuracy of the proposing method in comparison with the finite element method.
