| dc.description.abstractEn | Currently, almost all material manufacturing processes are simulated using methods based on continuum approaches such as the Finite Element Method (FEM). These methods, though widely studied, face difficulties with multi-body, contact, high-strain and high-displacement problems, which are usually found in manufacturing processes. In some cases, the Discrete Element Method (DEM) is used to overcome these problems, but it is not yet able to simulate some of the physics of a continuum material, such as 3D heat transfer. To carry out a realistic simulation of a process, its thermal eld must be properly predicted. This work describes a fast and efficient method to simulate heat conduction through a 3D continuum material using the Discrete Element Method. The material is modelled with spherical discrete elements of di erent sizes to obtain a compact and isotropic domain adequate for carrying out mechanical simulations to obtain straightforward thermal and mechanical coupling. Thermal simulations carried out with the proposed Discrete Element Method are compared to both the analytical and FEM results. This comparison shows excellent agreement and validates the proposed method. | |
