Model ID: 2198
This model simulates the insertion of a snap hook in its groove. Fasteners like this are common in the automotive industry, for example, in the control panel of a car. In this case it is important to know the force that must be applied in order to place the hook in the slot but also the force needed to remove it. From a numerical point of view, this is a highly nonlinear structural analysis, mainly due to the contact interaction between the hook and the slot, but also due to the elasto-plastic constitutive law selected for the hook, and finally due to the geometrical nonlinearity originating from the large displacement.
