Mode I crack problem in an inhomogeneous orthotropic medium

摘要

In the symmetric crack problem considered the material is both oriented and graded. The properties of the medium is assumed to vary monotonously in the x_1-direction, x_1 and x_2 are the principal axes of orthotropy, and the crack is located along the x_1-axis. The loading is such that x_2 = 0 is a plane of symmetry. The mode I crack problem for the inhomogeneous orthotropic plane is formulated and the solution is obtained for various loading conditions and material parameters.
