Abstract

Reduced integral is used widely to improve the efficiency of solver especially for nonlinear analysis at the cost of additional artificial strain energy, therefore, proper approach should be used to control the hourglass effect induced by reduced integral. Numerical results show that for Abaqus/Standard solver, stiffness mode of hourglass control can exhibit much better performance than the enhanced mode, but the enhanced method was the only proposal of Abaqus while using analysis continuation techniques. Results also show that the Standard solver may not present reasonable results under low level damping, thus the damping mode should be chosen carefully for structural analysis.
