A Coupled Thermo-Mechanical Model

$0.00

Description

Thermo-mechanical models are helpful in the study of the effects of a mechanical process on the material thermal behaviour and vice versa. One of the most common models is machining. Regarding machining, there are lots of proposed researches. In a study by Luke Berglind and Erdem Ozturk,  they focused on the process models used to simulate cutting forces, torques, form error, and tool dynamics throughout a part program. The other common model is studying the effect of car brakes on raising the temperature of the brakes. All in all, there are thousands of studies that require the use of thermo-mechanical simulations.

Using Abaqus for coupled models

Using Abaqus to develop a thermo-mechanical model is very common since it is very strong in predicting the strain and strain in elements. In Abaqus, these models are known as coupled thermal-displacement models because of the name of the created step. Based on Abaqus documentation, coupled models take a longer time to solve due to the stiffness of matrix. In fact, the created matrix can be twice as large as a decoupled model. This decreases time efficiency significantly and sometimes it might be better to use decoupled models.

Why Abaqus for thermo-mechanical models?

Abaqus is very flexible in creatung a model because of its available features. Furthermore, creating complex models are faster and easier by the subroutine code in Abaqus. The advantage of using multi-processors in Abaqus analysis offers higher time efficiency. Python scripting is another advantage of using Abaqus for parametric study. Using Python makes it possible to develop plugins or codes that facilitate the process of model creation.

More details about this product:

Like every other type of model, creating a simple thermo-mechanical model is a good start to learn developing complex models. A thermocouple model is one of the most common models to start learning couple models. In this video, you will learn how to create a simple coupled model by simulating a mechanical thermocouple which is straightforward. The video is short so you can learn this in less than 15 minutes and you will have the output and Abaqus CAE file.
