 Hyperelastic SealIn 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... Viscoplastic Creep in Solder JointsThis 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... Introduction to the Stuctural Mechanics ModuleThese 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... Temperature-Dependent Plasticity in Pressure VesselThis 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... Sheet Metal FormingThis 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... Elastoacoustic Effect in Rail SteelsThe 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... Necking of an Elastoplastic Metal BarA 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... Snap Hook 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... Compression of an Elastoplastic PipeIn 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... Elastoplastic Analysis of Plate with a Center HoleIn 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...
