A novel mathematical 3-D procedure to evaluate the interfacial state of stress in adhesively bonded scarf joints the general case of parabolic scarf surface

摘要

A mathematical procedure is developed to utilize the complementary energy method, by minimization, in order to obtain an approximate analytical solution to the 3-D stress distributions in bonded interfaces of dissimilar materials. In order to incorporate the effects of surface topography, the interface is expressed as a general surface in Cartesian coordinates. i.e.. F(x,y,z) = 0. In this paper, the parabolic interface problem, i.e., y = x{sup}2 surface is considered.
