TY - EJOU AU - Zhang, Ch. TI - A 2-D Time-Domain BIEM for Dynamic Analysis of Cracked Orthotropic Solids1 T2 - Computer Modeling in Engineering \& Sciences PY - 2002 VL - 3 IS - 3 SN - 1526-1506 AB - A 2-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 time-domain 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.
