| Popis: | This is a preprint of the paper. For the final version of this paper, please refer to International of Fracture; The paper investigates the peeling test of an elastic plastic film on an elastic substrate. The case of the film material presenting a saturation of the flow stress is considered. Based on earlier approaches of the literature , see for instance Kim and Aravas (1988) (Kim, K.S., Aravas, N., 1988, International Journal of Solids and Structures, 24, 417-435), a semi-analytical expression for the plastic dissipation during bending/reverse bending is proposed. The validity of the present expression is established based on finite element calculations. It is shown that for the interpretation of results of peeling test at 90 degrees when the peeling force and the curvature have been measured, the present approach provides a precise interface fracture energy. The comparison is made with predictions based on an elastic perfectly plastic approach. |
