Abstract
Numerical investigations were conducted on plane and axisymmetric convex joints of polycarbonate—aluminum and poly(methyl methacrylate)—aluminum interfaces to gain a better understanding of the stress state along the interface and also to aid an experimental study conducted on the same issue. Two-dimensional plane—stress investigations of convex joints revealed the successful elimination of the free-edge stress singulatities along the specimen width although stress singularities, along the thickness direction, persisted. A convex axisymmetric design, with the same material combination and joining angles, proves to be a better design in order to achieve an overall elimination of free-edge stress singularities of dissimilar materials and structures.
