EFFECT OF TEMPERATURE ON THE CONTACT STRESSES AND RESIDUAL BEARING STRENGTH OF PIN-LOADED COMPOSITE LAMINATES

摘要: Abstract Contact stresses and residual bearing strength of pin-loaded composite laminates at different temperatures are investigated. An incremental finite element code, based on the updated Lagrangian approach, was developed for determining contact near a hole in under combined thermal mechanical loadings. Based progressive damage model, quadratic theory with proposed failure simulation adopted predictions. In stress analyses, properties assumed to be temperature dependent. Numerical results include distributions initial (thermal) as well total around hole, strength, mode single-fastener clearance-fit joint an elastic pin. The strain model test has been performed elevated verification present calculations.
