Abstract

In this study, compression and recovery properties for metal gasket with straight sections and arc sections are studied by using the finite element method (FEM). When a metal gasket is subjected to clamp load, a contact width which is necessary for seal-up occurs due to flattening of the arcs. Then, the combination of the straight sections and the arc sections causes various deformation modes because the combination has a large effect on the characteristic of flattening. In other words, it is possible to control the flattening behaviour by adjusting the stiffness of the straight sections and the arc sections. Based on these facts, it is possible to propose a metal gasket in which the flattening occurs at the clamp load and the dent does not occur, furthermore, the clamp load does not descend very much at the tiny looseness.
