Investigation of 3-D friction coefficient in pinned composite plates
Journal Title: Scientific Journal of Pure and Applied Sciences - Year 2013, Vol 2, Issue 8
Abstract
Connecting composite materials to each other is of great importance. Mechanical joints are widely applied in industries; therefore they are of more attention in designers view. In this kind of joint, determinations of ultimate strength, type of rupture and stress analysis at pin location are vital. The aim of this paper is to study interlaminar stress in mechanical joints and the effect of different stacking sequences on generated stresses between layers and their stress distribution. The effect of friction on stresses between layers in composite plates is also investigated. The problem was modeled three dimensionally in ABAQUS software, considering interlaminar stresses, friction and different stacking sequence. As a result, some remarks are presented; for example: When sequence is symmetry, stress field is symmetry toward middle plate, too. In cross-ply layup, stress fields are symmetry toward bearing and mid-plane. Applying friction in different directions, it was seen that friction coefficient in direction was higher and more important than in other directions. As a result, radial and tangential stress diagrams for two condition of friction in z direction and without friction were so close and also stress diagrams for two condition of friction and have more similarity
