We stare the advance of numerical stress analysis program for building in wonder. Now, it is possible to get effective results of stress analysis from those program for behavior of nuclear plants by missile impact, and for local complex behavior of buildings under high-velocity loading. There are two methods for analytical scheme mainly. One is explict method and another is implicit method. We think that it is necessary to select analytical programs for these problems by considering wave propagation. In this report, we actually compared the diffirence from the mesh size of the model, and from the two analytical methods, by using simple canti-liver plate under impact loading. We use the material model as linear isotropic material for one case and as porfect plasticity with Von Mises criterion for another.
