Abstract
Analytical solutions are developed for stresses in an infinite orthotropic plate with smooth elastic pin under pin and plate loading. The pin could be of interference, push or clearance fit. A two-dimensional plane stress elastic analysis using a complex variable formulation in conjunction with equidistant boundary collocation scheme for satisfying boundary conditions is carried out. An inverse technique is used to obtain loads, stresses and displacements for a specified contact/separation configuration. Numerical results are presented which bring out the effect of pin modulus of elasticity and the degree of orthotropy of plate on bearing stress, hoop stress and load contact behaviour. The results indicate that decrease in the pin modulus of elasticity relative to that of the plate ( E p E 1 ) decreases the bearing stresses at the pin-plate interface.
