On some aspects of pin-loaded laminates

Some aspects of pin loaded laminates, including basic kinematics related to the contact angle and moving boundary, validity and applicability of cosine distribution of contact stress, e€ects of sti€ness ratios as well as clearance and friction are presented. Numerical results on the basis of a previously developed direct boundary element procedure, with a re®ned and improved computational algorithm with additional capabilities are given and used for discussing various aspects of pin-loaded orthotropic laminates. Empirical formulas based on generated computer results are suggeste
