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) mounted on a circuit board by means of several solder ball ...
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.
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 ...
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 elastoacoustic effect in steels typically used in railroad rails. ...
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 ...
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 ...
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 ...
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 the importance of understanding the hyperelastic behavior ...
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 the force needed to remove it. From a numerical point of view, ...
