<P>PROBLEM TO BE SOLVED: To estimate dent resistance at a portion such as a character line where a curvature changes steeply. <P>SOLUTION: A finite element analysis simulation is performed for a panel plate having a surface-shape steep portion in which a curvature changes steeply, using a panel shape condition of the panel plate and a material condition to be applied to the panel plate, so that an applied load in which plastic strain is generated on a plate surface of the surface-shape steep portion is acquired. Dent resistance at the surface-shape steep portion is evaluated based on the applied load. <P>COPYRIGHT: (C)2013,JPO&INPIT |
