時間域境界積分方程式法によるレーザ励起弾性波動の指向性に関する数値的検証

Directional characteristics of laser generated elastic waves are investigated. With time domain BIEM, we compute the thermally generated wave field in an aluminium test piece. We also eval-uate the velocity at inner points of the test piece. Directional characteristics of laser generated elastic waves are determined.
