• Contact stresses between two disks and a sandwiched solid-metal flat gasket are studied to discuss the sealing behavior of the gasket. Assuming that the gasket is an elastic body, the three dimensional theory of elasticity is used to analyse the contact stresses and the deformations in three laminated disks whose both sides are compressed by axisymmetrically distributed loads. By neglecting shearing stresses on the contact surfaces, an exact solution satisfying the remaining boundary conditions is obtained. Numerical calculations are carried out for various rigidities and thicknesses of the disks under various loading conditions. In order to examine the results of the theoretical analysis, the contact stress is measured experimentally by using pressure-sensitive pins attached to a disk. It is confirmed that the theoretical results agree well with the experimental ones except the vicinity of the loaded area.
