✦ Synopsis
A coupled Moire-finite element method is used to calculate displacement and strain fields around a elasto-plastically deformed crack tip. This hybrid approach is shown to be economical when compared with conventional iterative finite element procedures from the point of view of computational time and storage when analysing problems involving extensive plastic deformations. By supplying surface deformation boundary conditions, one could determine field quantities in the interior of the material. Hybrid method gives more accurate field descriptions than regular finite element schemes.
