THE EFFECT OF CONTACT AREA SHAPE AND PRESSURE DISTRIBUTION ON MULTILAYER SYSTEMS RESPONSE

Numerical analysis of stresses, strains, and displacements in multilayer systems for any shape of contact area and pressure distribution is presented. The scheme developed for microcomputers is made of two programs: one for evaluating the stresses and deformations under a point load and the second for performing the numerical integration of the point load solution. Results obtained by using the scheme for the uniformly distributed pressure, Boussinesq, and three-layer system cases were compared to those of analytical and other numerical solutions. They were revealed to be in excellent agreement. Results for a rectangular contact area and nonuniform pressure distribution are presented. The effect of the contact area and pressure distribution shapes on the design strains is illustrated and discussed. The scheme presented is preferable to the 3-D finite element analyses. It dispenses with the use of mainframe computers and is highly accurate.
