| Outline of Final Research Achievements |
In present research, a new numerical technique “MDP-FEM” for large deformation elastic plastic analysis was proposed. In “remeshing” which is often carried out to avoid excessive element distortionｓ, “data mapping” of strain history dependent physical quantities such as the stresses from old to new finite element analysis model is necessary. This course of investigation proposes the use of MDPs (Mesh-independent Data Points) which are distributed over the problem domain independently from the finite element mesh. With the MDPs, the data mapping is not necessary and arbitrary remeshings can be carried out.
