On the influence of eccentricity on Thick Adherend Shear Tests

Two main mechanical tests are commonly used to measure the critical shear stress of an adhesive, Single Lap Shear (SLS) test and Thick Adherend Test (TAST). In these tests, assessment is performed with mode mixity. this work, a two-dimensional Finite Element Model asymmetric TAST set-up few on titanium/epoxy specimens. The model takes into account shift adhesive joint loading axis. impact shifted estimated two specimen geometries though sensitivity analysis. Then, method suggested assess state that caused failure. results show failure location mixity can be tuned by shift. Furthermore, it shown standard geometry remarkably sensitive loading. As consequence, parameter should set submillimeter accuracy or modified version classical used. reported consistent one another provides clear link between stresses response until
