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

Viscoplastic Creep in Solder Joints

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 geometry includes two electronic components (chips) ... 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

Snap Hook

This example 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 and also ... 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

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

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

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 ... 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

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
