Abstract
This paper presents the results obtained with Dual Reciprocity Boundary
Element Formulation applied to dynamic problems. In spite of the generally
good performance, wave propagation problems demand still greater attention in
controlling the higher modes, especially under impact loading. To improve the
traction response, numerical simulations were done with three time integration
methods with parametric control of dissipation: the well-known Wilson-8
scheme, the HHT-a method and the recently devised CHL-p method.
1 Introduction
Dual Reciprocity (DR) is a technique of Boundary Element Method (BEM)
initially idealized for the solution of free vibration problems [I]. DR allows
obtaining the final matrix equations in a form simi
