Thermal Heat Transfer in Abaqus

One of the most rampant phenomena in the universe is heat transfer. Heat transfer can cause changes in mechanical characteristics. Heat transfer analysis can be divided into two types: consistent or transient. In this lesson, the settings and tips of these two analyses with examples are discussed.
Then, mechanical analyses under the effect of heat transfer analysis will be investigated. In some cases, these analyses (mechanical/ thermal) should become coupled simultaneously and, in some cases, can be performed consecutively. For each one, essential tips and items to detect problem type and usage method with related examples are presented. In the coupled process, hot forging analysis is presented as a workshop.
In some simulations, elements suffer from excessive distortion; In this case, you have to use the ALE technique. This technique is described entirely, and its difference with two methods, Lagrangian and Eulerian, is presented. This technique is used in the hot forging process; complete notes and steps to solve coupled include types of heat transfer, radiation, convection, conductivity, heat production caused by friction, heat production caused by plastic work, and dependency of elasticity and plasticity on heat is described.
In the second workshop, impact analysis is done. In this process, heat has a little time to distribute in the whole matter and, another type of heat transfer named adiabatic will be studied. This type of heat transfer and its applications are discussed thoroughly. The material in this process has used Johnson cook’s law, which mechanical characteristics depend on temperature and strain rate.
A full explanation of this model, along with the steps to implement on software, is described. Other matters in this example are investigating impact time, velocity changes according to the time chart of the bullet, the force, and the resultant torque graph of several elements and nodes.
