Numerical and Experimental Analysis of Exhaust Manifold Gasket

The paper presents experimental investigation and numerical simulation of a commercial exhaust manifold gasket. Non-linearities in geometric and material behavior make exhaust manifold gasket modeling quite complicated. In the paper, two different FE modeling techniques are compared in order to suggest the best modeling way. Experimental data are collected in order to validate the numerical models. Differences between the two modeling techniques are emphasized and a choice criterion is suggested.
