Plastic Deformation During the Expansion of a Biomedical Stent

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 procedure, a stent is deployed into the blood vessel by means of a balloon. The expanded stent acts as a scaffold that keeps the blood vessel open. During this ...

Hyperelastic Seal

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 conditions.

Elastoplastic Analysis of Holed Plate

In this example 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 plate. The example also shows you how to apply an external hardening function based on an interpolated stress-strain curve.

Arterial Wall Mechanics

This model shows how to implement an anisotropic hyperelastic material for modeling collagenous soft tissue in arterial walls. The hyperelastic material model, called Holzapfel-Gasser-Ogden material, is based on the article: Holzapfel, G. A., Gasser, T. C., & Ogden, R. W. (2000). A new constitutive framework for arterial wall mechanics and a comparative study of material models. Journal of ...

Necking of an Elastoplastic Metal Bar

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 ...

Temperature-Dependent Plasticity in Pressure Vessel

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 rapidly transfer cold water in case of an emergency cooling. The pressure vessel is made of carbon steel with an internal cladding of stainless steel. In case of ...

Sheet Metal Forming with Orthotropic Plasticity Hill '48

Metal Forming is the metalworking process of reshaping metal parts through mechanical deformation without adding or removing material. This is mainly based on plastic deformation that enables permanent deformation of the bodies. Here, a numerical simulation of the sheet metal forming process was carried out using an orthotropic material law for metal plasticity (Hill '48). Different forming ...

Compression of an Elastoplastic Pipe

In offshore applications, it is sometimes necessary to quickly seal a pipe as part of the prevention of a blowout. This example shows a simulation, in which a circular pipe is squeezed between two flat stiff indenters. The model serves as an example of an analysis with very large plastic strains and contact.

Combining Elastoplastic and Creep Material Models

This model shows how to combine different types of material nonlinearity, such as creep and elastoplasticity. In this specific example you will perform a stress and nonlinear strain analysis on a thick cylinder under a nonproportional loading: an initial temperature increase followed by a fluctuating pressure applied to the internal surface of the cylinder. This load case involves two ...

Stress Analysis of a Pressure Vessel

A pressure vessel is designed to hold liquids or gases at substantially higher or lower pressures than the ambient pressure. A high pressure difference requires a correct design in order to avoid catastrophic failures. The Stress Analysis of a Pressure Vessel app is an example of how you can design a tool for checking a family of components with a parameterizable geometry. The purpose of the ...
