Interfacial failure or delamination in a composite material can be simulated with a cohesive zone model (CZM). A key ingredient of a cohesive zone model is a traction-separation law that describes the softening in the cohesive zone near the delamination tip. This example shows the ... 詳細を見る

In a lithium metal battery, lithium metal is deposited during charging on the negative electrode. Mass transport and ohmic effects in the electrolyte cause small protrusions on the metal surface to be subjected to accelerated growth during charging. In worst case scenarios, this leads to ... 詳細を見る

This tutorial demonstrates how to integrate multiple Lumped Battery models into the Electrical Circuit interface. Two batteries are connected in series. Each battery is protected by a shunt resistances that is activated if the battery state-of-charge reaches below a certain threshold ... 詳細を見る

Recent advances in the fabrication of microfluidic systems require handling of live cells and other micro particles as well as mixing. All this can, for example, be achieved using acoustic radiation forces and the viscous drag from the streaming flow. Streaming: Due to the nonlinear ... 詳細を見る

This is the model of the acoustics in a particulate-filter-like system. Real systems, like diesel particulate filters (DPFs), are designed to remove/filter soot (diesel particles) from the exhaust of diesel engine vehicles. The porous medium in such systems are typically structured with ... 詳細を見る

A single cylinder reciprocating engine supported on hydrodynamic bearings is studied. A starting torque is applied to bring the engine to required rpm. The loading torque is switched on once the engine picks up speed. After the start-up, the engine operates on its own driven by the ... 詳細を見る

This example solves for the temperature distribution inside a vacuum flask holding hot coffee. The main purpose is to illustrate how to use MATLAB functions to define material properties and boundary conditions. 詳細を見る

This model simulates the propagation of a positive streamer in a weak electric field where the process of photoionization is essential to provide seed electrons at the front of the streamer head. The simulated electric field and electron density as a function of time agree well with that ... 詳細を見る

When a temperature gradient in a gas exists, suspended particles will tend to move from regions of high temperature to low. The force which produces this effect is called the thermophoretic force. Gas molecules colliding with a particle from the hot side have a higher velocity than the ... 詳細を見る
