Plastic Deformation During the Expansion of a Biomedical Stent - new

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 ...

Compression of an Elastoplastic Pipe - new

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.

Arterial Wall Mechanics - new

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 ...

Hyperelastic Seal - new

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.

Inflation of a Spherical Rubber Balloon - new

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 research, and the medical device industry, thus the importance of understanding the hyperelastic behavior during balloon inflations. The example is taken from ...

Snap Hook - new

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, ...

Viscoplastic Creep in Solder Joints - new

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 model geometry includes two electronic components (chips) mounted on a circuit board by means of several solder ball joints. Significant plastic flow clearly ...

Necking of an Elastoplastic Metal Bar - new

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 - new

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 a ...

Sheet Metal Forming - new

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 modeled in order to compute the forming angle (at the maximum punch displacement) and the angle after the punch release. Experimental data are available for ...
