Numerical analysis of stresses in adherend of single-lap adhesive joints

This paper deals with modelling of single lap adhesive bonded joints, at which true physical characteristics of adhesive have been considered and lap length has been changed. The experimental specimens have been made of two types of adherend material: stainless steel X5CrNi18-10 and aluminium Al99.5. Dimensions of prepared adherend plates are a b s = 30  90  1, 95 mm. All bonded joints have been realized using an engineering two-component epoxy adhesive. Such prepared joints have been stretched up to the break in the jaws of the tensile testing machine. The true diagram of stresses of adherend (metals) has been considered and comparison of data (applied force vs. end displacement) obtained with numerical analysis and experimental investigation. The results of both of them are in a good correlation. This investigation is a part of continuously testing of adhesive bonded joints.
