Cracking of a Notched Beam

In this example, two model for brittle damage are used to evaluate the fracture of a notched concrete beam subjected to three point bending. The results are compared with experimental data. Saiba Mais

Uniaxial Loading of Shape Memory Alloy

These models are a compilation of the examples in the text book Shape Memory Alloys: Modeling and Engineering Applications. D. Lagoudas Ed. Springer 2008. Saiba Mais

Lemaitre-Chaboche Viscoplastic Model

Most metals and alloys undergo viscoplastic deformation at high temperatures. In case of cyclic loading, a constitutive law with both isotropic and kinematic hardening is necessary to describe effects such as ratcheting, cyclic softening/hardening, and stress relaxation. The Lemaitre ... Saiba Mais

Inflation of a Spherical Rubber Balloon

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 ... Saiba Mais

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 ... Saiba Mais

Shape Memory Alloy Self-Expanding Stent

Stents are used in biomedical applications to support the inner wall of veins and arteries. Self-expanding stents made of shape memory alloys work differently from balloon-inflated stents, as these stents are crimped to the artery diameter at low temperature then released while the blood ...

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 ... Saiba Mais

Elastoacoustic Effect in Rail Steel

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 within structures. This example studies the ... Saiba Mais

Polynomial Hyperelastic Model

This model shows how you can implement a user defined hyperelastic material, using the strain density energy function. The model used is a general Mooney-Rivlin hyperelastic material model defined by a polynomial. In this example, you will see two material models based on the defined ... Saiba Mais

Arterial Wall Viscoelasticity

Anisotropic hyperelastic materials are used for modeling collagenous soft tissue in arterial walls. The arterial _wall_ mechanics application describes a section of an artery based on the Holzapfel-Gasser-Ogden hyperelastic material model. In this example the dynamic behavior of the ... Saiba Mais
