In this example, the homogenized elastic and viscoelastic properties of a particulate composite are computed based on the individual properties of elastic particles embedded in a viscoelastic matrix. Periodic boundary conditions are applied to a unit cell of the particulate composite ... En savoir plus
This tutorial demonstrates how to set up a simple static structural analysis. The analysis is exemplified on a combination wrench during the application of torque on a bolt. Despite its simplicity, and the fact that very few engineers would run a structural analysis before trying to turn ... En savoir plus
This example models the behavior of soil during a tunnel excavation. The surface settlement and the width of the plastic region around the tunnel are important parameters needed to predict required reinforcements during the excavation. Two study steps are used. The first study computes ... En savoir plus
In this tutorial example, the concepts of Component Mode Synthesis (CMS) are introduced through a simple solid model of a cantilever beam. Parts of the beam are reduced by the CMS technique. It is, furthermore, shown how CMS can be used to represent both the static and dynamic behavior ... En savoir plus
When a conductive solid material moves through a static magnetic field, an eddy current is induced. The current that flows through the conductor, which is itself moving through the magnetic field, induces a Lorentz force back on the solid. Therefore, a conductive solid that is vibrating ...

This example models heat generation in a beam-like structure subjected to small amplitude vibrations. The model computes the linear elastic response in the frequency domain. The transient heat-transfer analysis simulates the slow-rising temperature in the beam using the heat generated ... En savoir plus
Small heating circuits find use in many applications. For example, in manufacturing processes, they heat up reactive fluids. The device in this tutorial example consists of an electrically resistive layer deposited on a glass plate. The layer results in Joule heating when a voltage is ... En savoir plus
In this tutorial model, different methods for modeling brittle damage are compared in a simple model of a uniaxially loaded bar. The localization of the deformation during fracture is studied using different discretization orders and regularization methods. En savoir plus
This model demonstrates how the Free Shape Boundary feature can be used to perform shape optimization on a design found with topology optimization. The model uses the same objective and constraint as the original, which results in a slightly higher stiffness for the same mass. En savoir plus
Liquid or gas acoustics coupled to structural objects such as membranes, plates or solids are important applications in many engineering fields. This model is a general demonstration of an acoustic fluid phenomenon in 3D that is coupled to a solid object. The walls of the solid object ... En savoir plus
