Abstract

Abstract Transient elastodynamic crack analysis by time-domain boundary element method (BEM) is presented. Time-dependent traction boundary integral equations (BIEs) are used for this purpose. Both the hypersingular and the non-hypersingular formulations are dealt with. The time-domain traction BIEs are solved numerically by a time-stepping scheme. The efficiency and the accuracy of the time-domain BEM for transient elastodynamic crack analysis are demonstrated by a numerical example. Advantages and drawbacks of the hypersingular and the non-hypersingular BEM formulations are compared and discussed.
