Abstract
Car body is a very large and complex structure. To determine the stresses and deformation requires the aid of numerical tools such as package program. The SAP90 offers the capability of static and dynamic analysis of complex structures. This paper attempts to show some results of the modeling and the stresses calculation of car body by SAP90 on static and dynamic loads. The results of car body calculation under load acting from road surface determine natural frequencies, mode shapes of structure in order to examine car body.
