ANALYTICAL SOLUTIONS FOR LOAD-TRANSFER THROUGH SMOOTH ELASTIC PIN IN AN INFINITE ORTHOTROPIC PLATE

Analytical solutions are developed for stresses in an infinite orthotr opic plate with smooth elastic pin under pin and plate loading. The pi n could be of interference, push or clearance fit. A two-dimensional p lane stress elastic analysis using a complex variable formulation in c onjunction with equidistant boundary collocation scheme for satisfying boundary conditions is carried out. An inverse technique is used to o btain loads, stresses and displacements for a specified contact/separa tion configuration. Numerical results are presented which bring out th e effect of pin modulus of elasticity and the degree of orthotropy of plate on bearing stress, hoop stress and load contact behaviour. The r esults indicate that decrease in the pin modulus of elasticity relativ e to that of the plate (E(p)/E(1)) decreases the bearing stresses at t he pin-plate interface.
