Abstract

The aim of this presentation is to show the methodology used for a Dynamic Implicit Analysis applied to the Operational Shock loading condition, defined by RTCA/DO-160G, applied to an elastomeric bearing.
The approach to dynamic/implicit analysis will be investigated, presenting the different possibilities in the Abaqus solver that were tested and the resulting outcomes.
In particular, a comparison is made between the result obtained with the Quasi-Static solver and that obtained with the Hilber-Hughes-Taylor operator (Transient Fidelity and Moderate Dissipation). Within those frameworks, the influence of both physical and numerical parameters is investigated: interactions (ties or contacts), time increment (increasing or decreasing), load direction and damping (both material and numerical).
