dc.description.abstract | Recently, interest in the laser welding to assemble components of the auto-body has increased in the automotive industry due to its productivity, efficiency and reliability. When car crash occurs, crash performance and deformation mode of the auto-body are changed according to the location and shape of laser welds. In order to understand the crash behavior of auto-body through the FE analysis, the laser welded parts should be modeled physically compatibly and simply. This paper evaluates the compatible FE modeling technique for laser welds in crash analyses. A single laser welded part in a stich shape is modeled by a group of numerous beam elements or hexahedron elements. FE analyses of cross tension test and lap-shear test under the quasi-static condition were carried out according to the number of elements, panel mesh size, and the relative position of the laser weld to the panel mesh. From the comparison between experiment and analysis results which are load and displacement curve, suitable modeling technique, which has hardly influence on analysis results, for laser welds in crash analyses is suggested. | - |
