Stresses around a pin-loaded hole in orthotropic plates with arbitrary loading direction

Abstract

Lekhnitskii's method of complex stress function is extensively used to solve the pin-loaded circular hole problem in an infinite orthotropic plate. The approach is similar to the one used earlier by the authors, but extended into a more general fashion. The direction of pin-load is arbitrary and the presence of friction is considered. An analytic solution which satisfies the major displacement boundary conditions on the pin-loaded hole has been obtained. Certain parameters are introduced for simplifying the expressions. These formulas can be used for computing the stress distribution around a pin-loaded hole and estimating the effect of direction of the pin-load and the presence of friction. The degree of such an effect depends on the orthotropy of the material. Some numerical results have been calculated and presented in this paper. They are compared with other results available in the literature.
