Bracket - Transient Analysis

The bracket models are used as an introduction to structural mechanics modeling with the Structural Mechanics Module. The following features are introduced: * The fundamentals: static linear analysis * Parametric study * Including initial strain * Modeling thermal expansion * Adding a rigid connector * Adding spring conditions * Modeling with the *Shell* interface * Transient analysis * ...

Heating Circuit

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 applied to the circuit, which results in a structural deformation. The layer’s properties determine the amount ...

Fluid-Structure Interaction in a Network of Blood Vessels

This model refers to a portion of the vascular system of a young child - the upper part of the aorta artery. The blood vessels are embedded in a biological tissue (the cardiac muscle) and, during the flow of blood, pressure is applied to the internal surfaces producing deformation of the vessel walls. The complete analysis consists of two distinct but coupled procedures: a fluid-dynamics ...

Acoustic-Structure Interaction

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 are impacted by the acoustic pressure. The frequency response from the solid is calculated, which is then fed ...

Piezoacoustic Transducer

A piezoelectric transducer can be used either to transform an electric current to an acoustic pressure field or, the opposite, to produce an electric current from an acoustic field. These devices are generally useful for applications that require the generation of sound in air and liquids. Examples of such applications include phased array microphones, ultrasound equipment, inkjet droplet ...

Thermal Actuator

This tutorial model of a two-hot-arm thermal actuator couples three different physics phenomena: electric current conduction, heat conduction with heat generation, and structural stresses and strains due to thermal expansion. In this model version, the geometry is parameterized so that the effect of varying the actuator's dimensions can be analyzed.

Vibration Analysis of a Thick Beam

This model studies free and forced vibrations of a deep beam. The solution for eigenfrequency, frequency response and transient analysis are computed using a Timoshenko beam and compared with analytical results.

Vibrating Beam in Fluid Flow

A classical flow pattern is the von Kármán vortex street that can form as fluid flows past an object. These vortices may induce vibrations in the object. This problem involves a fluid-structure interaction where the large deformation affect the flow path. The magnitude and the frequencies of the oscillation generated by the fluid around the structure is computed and compared with the values ...

Piezoelectric Shear-Actuated Beam

The model performs a static analysis on a piezoelectric actuator based on the movement of a cantilever beam, using the Piezoelectric Devices predefined multiphysics interface. Inspired by work done by V. Piefort and A. Benjeddou, it models a sandwich beam using the shear mode of the piezoelectric material to deflect the tip.

Vibrating Membrane

The natural frequencies of a prestressed circular membrane are computed and compared with analytical solutions. Two method are used: In the first study the prestress is given explicitly, while in the second study an external load provides the prestress.
