An analysis of a crack with bridging fibers in an orthotropic elastic infinite plate is carried out. Based on Lekhnitskii's anisotropic elastic theory, the distributions of the stress and the displacement of the orthotropic elastic infinite plate with a crack are analyzed under a uniform remote tension stress. As well as utilizing the model of fiber pull-out, the relationship between the traction force at a bridging fiber and the crack opening displacement is established. The stress intensity factor K_I and the strain energy release rate G_I of the crack are obtained by linear elastic fracture mechanics, and the influence factor B_K of the bridging for the stress intensity is defined. Finally, in order to discuss the effectiveness of the present method, an example problem, the finite element method solution of which was given, is numerically solved.
