A circular metal bar is subjected to uniaxial tension. As an effect, large plastic strains develop. The material is elastoplastic with nonlinear isotropic hardening. As the elongation is increased, the decrease in radius becomes strongly nonuniform, so called "necking". The development ... 詳細を見る
This example illustrates how to perform eigenfrequency and static analyses of a ladder frame structure for a light truck. Important modeling strategies are described. For example, how to convert a solid geometry to a shell model, how to make different types of connections, and how to ... 詳細を見る
The elastic cantilever beam is one of the elementary structures used in MEMS designs. This model shows the bending of a cantilever beam under an applied electrostatic load. The model solves the deformation of the beam under an applied voltage. 詳細を見る
A hinge between two mechanical components is modeled by coupling two rigid connectors. This method can be used for simulating many types of mechanisms. In mechanical assemblies, parts are sometimes connected so that they are free to move relative to each other in one or more degrees of ... 詳細を見る
This model shows how to set up a uniaxial compression test on a prestressed soil sample. Due to uniaxial compression and simple initial stress values, it is possible to determine the vertical yield stress analytically. The soil sample is modeled with soil plasticity and the Mohr–Coulomb ... 詳細を見る
A square airbag made of a hyperelastic, compressible neo-Hookean material is inflated using pressurized air. Compressive stresses trigger wrinkling in some regions of the thin airbag. In this example, the wrinkling behavior is modeled using tension field theory, which gives a correct ... 詳細を見る
A square airbag is inflated using constant air pressure. In some regions of the airbag the material wrinkles during inflation, as negative principal stresses develop. The wrinkling membrane model within the tension field theory gives a correct description of the stress distribution and ... 詳細を見る
Indentation tests are commonly used to evaluate the safety of battery cells by assessing the risk of internal short circuits under external mechanical loads. This example demonstrates how to set up such a test, in which an indenter is pressed onto a battery cell, causing large ... 詳細を見る
This model illustrates the modeling of slider motion caused by a base rotation. The motion of the slider is analyzed under various forces such as inertia force, centrifugal force, spring force and damping force. The prismatic joint, which is used to connect the two components, is spring ... 詳細を見る
An acousto-optic modulator (AOM) is a device which can be used for controlling the power, frequency or spatial direction of a laser beam with an electrical drive signal. It is based on the acousto-optic effect, that is, the modification of the refractive index by the oscillating ... 詳細を見る
