Finite Element Analysis of Finite Strain Elastoplastic Contact-Impact Problems
In this study a finite element analysis of elastoplastic contact-impact has been carried out. Newmark, Wilson-q, Central Difference and Houbolt Methods have been used as direct integration methods. Impact analysis includes elastoplastic and large deformation based upon updated Lagrangian including buckling check. The results show that the direct integration methods give different results due to different contact-impact cases. Plastic analysis is more stable than the elastic analysis.
