| [en] The additive manufacturing (AM) is suitable approach for manufacturing of complex metal
parts in future. Thermal strain and stress play vital role in characteristic of manufactured metal part. After the laser creates melt pool in metal powder bed, thermal strain and residual stress come into play in solidified melt pool during cooling down and reheating of material. In the course of complete process, the material properties are also function of temperature. So in this contribution, modelling and solution of energy balance equation tracks down the evolution of temperature profile. For structural analysis, the elasto-plastic material is assumed. The thermal loads due to thermal conduction are applied at the specimen under production, which results in elasto-plastic deformation. The Finite Element Analysis (FEA) platform FEniCS [1] is utilized for the simulation of models under consideration. It predicts the part-scale temperature profile and the residual distortion displacements in result of permanent deformation in solidified melt pool. In result, the thermomechanical analysis platform is settled and also its application is widened by activating the finite elements in domain for layer by layer addition of material. Which now has to be further developed for advanced elements activation strategy [2]. | |
