Necking of an Elastoplastic Metal Bar
Application ID: 12607
A circular metal bar of elasto-plastic material with nonlinear isotropic hardening behavior is subjected to uniaxial tension. Affected by significant stresses the bar experiences high plasticity. The phenomenon of necking is captured and its growth is accurately simulated. The change in radius is in good agreement with results found other literature. This example is a classical benchmark for large strain plasticity codes.
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.
