Large Deformation Analysis of Hyperelastic Materials Using SPH Method

抄録

The importance of large deformation problems in the manufacture of rubber products is increasing. Thus far, these deformations can be analyzed by FEM. However, large deformation cause severe mesh distortions in elements near the boundary, thereby reducing the stable time increment while obtaining the solution. On the other hand, particle methods are meshless techniques that no longer use connectivity data. Therefore, users do not encounter such problems.
