| Abstract: |
| The explicit time integration for the finite element non\|linear analysis is available when the implicit technique suffers some difficulty with static process in the solid and structural mechanics. The key factor in this slow\|dynamic technique is how to choose the load duration and minimize the undesired dynamic effect originated from the inertia force of the governing equation. In this paper, five time history profiles have applied and its techniques and guidelines are presented. The effect of the duration and functional from of the time histories of loads and boundary conditions is quantified by the analysis of a linear spring mass oscillator. The resulting guidelines and techniques are successfully demonstrated in the non\|linear finite element simulation of plane stress for the sheet plate operation. The error measures that quantify the dynamic effect are also discussed. Some valuable suggestion is given in this researching field. |
