Finite element analysis of conventional car door model for impact test using solidworks ®

The demand for car that is lightweight and high safety has increasing and provides challenge in automotive industry. In order to fulfill those criteria, the selection of the materials is important. To find light materials that is strong enough to be used as car door, 3 materials were chosen which is steel alloy, aluminum alloy and carbon fiber composite. By using SolidWorks®, a model was built and finite element analysis for impact test was run to study their properties to see their potential as car door. Based on the analysis and the reading of stress and displacement, composite material have the lowest mass and have the highest strength compared to other materials. So composite is the best materials that can be used to make a car door.
