자동차 충돌해석을 위한 유한요소모델링 시스템의 개발

A finite element modeling system for crash analysis of automobiles has been developed. The system. AutoPnP, is composed of a pre-processor and a post-processor, and is designed to be linked to AutoCrash. an explicit finite element analysis program developed for crash analysis. The entire system is composed of GUI and a mesh generating module and a post-processing module. As for surface mesh generation, both structured and unstructured quadrilateral shell elements can be constructed on 3D surfaces that involves planar, cylindrical. blending and B-spline surfaces, while for volume mesh generation hexahedral elements with sections of both uniform and nonuniform quadrilaterals can be constructed. Post-processing module includes XY-plotting and filtering, mesh display and deformed shape display.
