Abstract

<p>The purpose of this report is to examine the applicability of a causality-based damping model in which the damping ratio is constant over a wide frequency band to the dynamic explicit method.First, we give an overview of the causality-based damping model and an overview of the dynamic explicit method that approximates the velocity term by receding difference. Furthermore, in the linear elasticity problem, numerical analysis was performed using a finite element model assuming a real scale, and the applicability was examined.</p>
