Elastic–plastic analysis of the peel test for ductile thin film presenting a saturation of the yield stress

The paper investigates the peel test of an elastic–plastic film on an elastic substrate. The case of a film material presenting a saturation of the yield stress is considered. Based on earlier approaches of the literature, see for instance Kim and Aravas (Int J Solids Struct 24:417–435, 1988), a sem...

Description
Summary:The paper investigates the peel test of an elastic–plastic film on an elastic substrate. The case of a film material presenting a saturation of the yield stress is considered. Based on earlier approaches of the literature, see for instance Kim and Aravas (Int J Solids Struct 24:417–435, 1988), a semi-analytical expression for the work done by bending plasticity is proposed. The validity of the present expression is established based on finite element calculations. It is shown that for the interpretation of the results of peel test at 90 ∘ when the peel force and the curvature are measured, the present approach can provide a precise value of the interface fracture energy.
