In this model you study the force-deflection relation of a car door seal made from a soft rubber material. The model uses a hyperelastic material model together with formulations that can account for the large deformations and contact...
This example studies viscoplastic creep in solder joints under thermal loading using the Anand viscoplasticity model, which is suitable for large, isotropic, viscoplastic deformations in combination with small elastic deformations. The...
These models are used for an introduction to structural mechanics modeling using the structural mechanics module. The following features are introduced: - The Fundamentals: A Static Linear Analysis - Parametric study - Including...
This example is a NAFEMS validation model of a friction contact problem with an elastoplastic material model. A thin metal sheet is being forced into a die by a punch. Both the compressing displacement and the release of the punch are...
This example demonstrates how to use temperature dependent materials within the Nonlinear Structural Materials Module. A large container holds pressurized hot water. Several pipes are attached to the pressure vessel. Those pipes can...
The elastoacoustic effect is a change in the speed of elastic waves that propagate in a structure undergoing static elastic deformations. The effect is used in many ultrasonic techniques for nondestructive testing of prestressed states...
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...
A stent is a wire-mesh tube used to open a coronary artery during angioplasty, a process for the removal or compression of plaque. Their design is of significance for percutaneous transluminal angioplasty with stenting. During this...
In this model you analyze a perforated plate loaded into the plastic regime. In addition to the original problem, which you can find in section 7.10 of The Finite Element Method by O.C. Zienkiewicz, you can also study the unloading of the...
This model aims to investigate the inflation of a rubber balloon with different hyperelastic material models, and compare the results to analytical expressions. A controlled inflation could benefit clinical applications, cardiovascular...
