Abstract
Finite difference method is used to analyze the axisymmetric problem of smooth contact between a rigid indenter and a laminated circular plate clamped at the edges. The plate is assumed to be made up of transversely isotropic layers. The numerical study shows that interlaminar shear stresses in the vicinity of contact are much different from the laminate plate theory solutions, and that low-modulus surface layers and in terlayers can help in reducing the maximum interlaminar shear stresses due to static inden tation.Keywords
