Application ID: 2198
This example 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 and also the force needed to remove it. From a numerical point of view, this is a highly nonlinear structural analysis, due to the contact interaction between the hook and the slot, the elasto-plastic constitutive law selected for the hook, and the geometrical nonlinearity originated from the large displacement.
This model example illustrates applications of this type that would nominally be built using the following products:非線形構造材料モジュール
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
- COMSOL Multiphysics® and
- either the ジオメカニクスモジュール, or 非線形構造材料モジュール and
- either the MEMSモジュール, or 構造力学モジュール
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the 製品仕様一覧 and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
