An isothermal single particle model formulation for a lithium-ion battery is presented in this work. The single particle model is a simplification of the 1D formulation for a lithium-ion battery along with a few assumptions. The model is typically valid for low-medium current scenarios. ...

Interference fit is a technique used to join or fit one part over or around another part. The internal part is cooled, so that it shrinks, and is then fitted. Once the part heats up again and expands, a contact pressure builds up at the interface between the two parts. This type of ... Mehr lesen
This example demonstrates the wrinkling phenomenon in a thin sheet stretched uniaxially. The modified membrane theory, which incorporates the wrinkling model, ensures noncompressive principal stresses in the wrinkled region. The analytical results are compared to the numerical results. Mehr lesen
This example shows the analysis of a perforated plate loaded into the plastic regime. The purpose of the analysis is to demonstrate how plastic strains can be mapped between dissimilar meshes. Mehr lesen
For several high-precision applications, especially in hydraulic systems and fuel injectors, micro bores are needed. In most cases the shape of the injection hole, especially the edge rounding, has a significant influence on the atomization of fluids and therefore on the combustion ... Mehr lesen
The drive for miniaturizing electronic devices has resulted in today’s extensive use of surface-mount electronic components. An important aspect in electronics design and the choice of materials is a product’s durability and lifetime. For surface-mount resistors and other components ... Mehr lesen
Obwohl sie ursprünglich für den Einsatz in Druckern erfunden wurden, sind Tintenstrahldüsen inzwischen auch in anderen Anwendungsbereichen wie den Biowissenschaften und der Mikroelektronik zu finden. Simulationen können nützlich sein, um das Verständnis der Strömung zu verbessern und das ... Mehr lesen
In this example, the Bergstrom–Boyce material model is used to capture the nonequilibrium behavior of carbon-black-filled chloroprene rubber under a strain history that alternates compression with relaxation. Results are verified against experimental and numerical results taken from ... Mehr lesen
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
At the macroscopic level, systems usually mix fluids using mechanical actuators or turbulent 3D flow. At the microscale level, however, neither of these approaches is practical or even possible. This model demonstrates the mixing of fluids using laminar-layered flow in a MEMS mixer. This ... Mehr lesen
