Thermo-mechanical models are helpful to study the effect 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 breaks on raising the temperature of the brakes. Furthermore, there are thousands of studies that require to 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 takes a longer time to solve due to the stiffness matrix. In fact, the created matrix can be twice larger as a decoupled model. This increases time efficiency significantly that sometimes it might be better to use decoupled models.
Why Abaqus for thermo-mechanical models
Abaqus is very flexible to create a model because of the available features. Furthermore, creating complex models are faster and easier by using the subroutine code in Abaqus. The advantage of using multi-processors in Abaqus analyzes gives the possibility of having higher time efficiency. Python scripting is another advantage of using Abaqus for parametric study. By using Python, it is possible to develop plugins or codes to facilitate the process of creating a model.
Mode details about this product:
Live every other type of model, creating a simple thermo-mechanical model is a good start to learn developing a complex model. A thermocouple model is one of the most common studies to strat learning couple models. In this video, you will learn how to create a simple coupled model by simulation a mechanical thermocouple witch 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.
