CM-JP-1 Structural Analysis using SPH Method

抄録

SPH simulation is a meshless Lagrangian technique which is appealing as a possible alternative to Numeric techniques currently used to analyze complicated structures,fracture of materials and high deformation events.In the present study,the SPH algorithm has been developed to elasto-plastic analysis and fracture analysis in the field of solid dynamics.In this study data generation technique for large scale structures has been also developed.The accuracy of SPH method is important when the method is used for industrial design of structures.It is cleared that the accuracy of SPH method is basically 2nd order and the results have sufficient accuracy comparing with the results of standard FEM code(LS-dyna).SPH method is suite for computing fracture of solid materials because of the meshless algorithm and successfully applicable to crackpropagation problems of practical use.
