The Large Deformation Analysis

Abstract

The concept of cover is employed from manifold method into voxel analysis and applied to nonlinear analysis of 3D solid structure. To overcome the problem of locking due to distorted element in large deformation analysis of solid structure, remeshing technique using voxel cover is proposed. Also, the treatment of the boundary conditions is discussed, and the technique of balancing forces at the displacement boundary conditions is proposed. The separate analysis model and geometric model whose shape is updated as the analysis proceed are used for the easy re-generation of analysis model.
