摘要: Abstract The problem of an elastic cylinder in normal contact between transversely isotropic layered substrate surfaces is investigated using the finite element method (FEM). A two-dimensional model developed which accurately determines stress, length, and approach distance surfaces. Numerical results, are initially verified Hertzian theory, obtained at 756 distinct conditions by varying coating material, thickness, load, radius, material. numerical results normalized with respect to theory a dimensionless anisotropic material parameter, ζ, introduced. expressions for maximum subsequently determined curve-fitting simulations performed. relevance such ascertained discussed comparing predicted layer presented Gupta Walowit [P.K.
