The efficiency of direct integration methods in elastic contact-impact problems

摘要

A comparison of direct integration methods is made and their efficiency is investigated for impact problems. Newmark, Wilson-θ, Central Difference and Houbolt Methods are used as direct integration methods. Impact analysis includes that of elastic and large deformation based upon updated Lagrangian including buckling check. The results show that the direct integration methods give different results in different contact-impact cases.
