A 2-D Time-Domain BIEM for Dynamic Analysis of Cracked Orthotropic Solids 

 -  Computer Modeling in Engineering & Science, 3, p.381-398, 2002 .
<br/><br/> A2-D time-domain boundary integral equation method (BIEM)for transient dynamic analysis of cracked orthotropic solids is presented in this paper. A finite crack in an unbounded orthotropic solid subjected to an impact loading is considered. Hypersingular timedomain traction boundary integral equations (BIEs)are applied in the analysis. A time-stepping scheme is developed for solving the hypersingular time-domain traction BIEs. The scheme uses a convolution quadrature formula for temporal and a Galerkin method for spatial discretizations. Numerical examples are given to show that the presented time-domain BIEM is highly efficient and accurate.
