Abstract

An assumed displacement hybrid finite element procedure developed specifically for treating mixed-mode behavior of cracks was used to solve two-dimensional problems in fracture mechanics involving anisotropic, nonhomogeneous but linearly elastic materials. The procedure was then checked by analyzing problems with known solutions which include centrally cracked isotropic and orthotropic tension plates, single-edge-notched tension plate, oblique edgenotched tension plate, and tension plates with one-quarter circular crack and subjected to uniaxial or biaxial tension. Also a doubly edge-cracked orthotropic tension plate and an orthotropic three point bend specimen, for which theoretical solutions are not available, were analyzed.
