Effect of adherend shape on stress concentration reduction of adhesively single lap joint
Keywords:adhesive, adherend, single lap joints, finite element
AbstractIn this work, the effect of adherend shape on the tensile strength of adhesively bonded single lap aluminum structures joint was numerically studied using three dimensional finite element models. Six joint models were investigated. In this paper, a static finite element analysis was performed in ANSYS considering geometric nonlinearities. The results show that the adherend geometry has the highest effect on peel and shear stresses. Similarly, for rounded and/or tapered geometries, adhesive material properties also cause a higher percent reduction in stress concentration.
