On the Temperature Dependent Mechanical Response of Dynamically-loaded Shear-dominated Adhesive Structures

A mode II mechanical characterisation of the adhesive joints is performed testing shear lap joint specimens in a Split Hopkinson Tensile Bar (SHTB), equipped with temperature chamber. The experimentallyobtained traction-separation curves were used to develop Cohesive Zone Model (CZM) capable representing strain-rate and temperaturedependent response joints. To validate model, End Notch Flexure (ENF) multi-material made from titanium carbon fibre reinforced polymer composite laminates tested at different temperatures using Pressure setup an in-house finite element (FE) simulations such tests employing developed CZM showed model’s ability accurately predict joints’ failure as well understand sequence combinations.
