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 ... Mehr lesen
Coriolis flowmeters, also known as mass flowmeters or inertial flowmeters, measure the mass flow rate of a fluid traveling through it. It makes use of the fact that the fluid's inertia through an oscillating tube causes the tube to twist in proportion to the mass flow rate. Typically, ... Mehr lesen
This tutorial shows how to include local nonlinear effects when simulating the acoustics of an exponential horn. Nonlinear effects become important when an acoustic horn is used for high amplitude signaling. The Nonlinear Acoustics (Westervelt) Contributions feature available for the ... Mehr lesen
This tutorial demonstrates how to model the interaction between an acoustic field and the heat release from a flame, using the Flame Model domain feature. Modeling this interaction is important in order to understand and predict unstable acoustic modes in gas turbines and jet engines. ... Mehr lesen
This model showcases how to solve for the scattered field when knowing the incident field for three different types of scatterer, i.e. an infinitely rigid one, a cavity and an elastic inclusion. This formulation can be useful when the scatterer is in the far-field of the source, such ... Mehr lesen
This tutorial model demonstrates how to estimate the material parameters of a combined hardening elastoplastic material model given cyclic shear data. Mehr lesen
This model analyzes the operation of a micromirror in air and the effects of thermoviscous damping on the vibration response. The model includes thermal losses in the structure as well as thermoviscous acoustic phenomena. The model couples the Thermoelasticity multiphysics interface to ... Mehr lesen
Fatigue testing of nonlinear materials with creep mechanism is a time-consuming process. In accelerated life testing the experiment time is greatly reduced by subjecting the material to testing conditions in excess of the operating one. In the model an aggressive thermal load cycle is ... Mehr lesen
A load carrying component of a structure is subjected to multi-axial cyclic loading during which localized yielding of the material occurs. In this model you perform a low cycle fatigue analysis of the part based on the Smith-Watson-Topper (SWT) model. Due to localized yielding, you ... Mehr lesen
In this tutorial model, a step thrust bearing is shape optimized to maximize the bearing capacity. A step thrust bearing consists of a stepped bearing surface on which the end of the shaft rotates. The entire assembly is submerged in a lubricant. The shaft collar is assumed to be ... Mehr lesen
