Stresses around pin-loaded hole in composite laminates using direct boundary element method

This study is concerned with stresses around a pin!loaded hole in symmetrically stacked composite laminates of _nite size using a two!dimensional direct boundary element method[ E}ects of friction and clearance between the pin and hole edge on the stresses are accounted for[ Also geometric compatibility and force constraint between the pin and the plate are enforced[ A new relation for geometric compatibility is proposed[ Stress distributions and the contact angle with slip and no!slip regions around the pin!loaded hole corresponding to various parameters are investigated[ Some interesting results are obtained[ The present method is e}ective and simple to use which can be implemented with a personal computer[ 0887 Elsevier Science Ltd[ All rights reserved[
