Numerical simulation of heat transfer, fluid flow and elements diffusion during laser welding of dissimilar steels
2017
The design of new steel grades offering equivalent mechanical performances for lower thicknesses and the added value with the possibility to join two different steel grades, require development and control of joining processes. Thanks to high precision and good flexibility, the laser welding became one of the most used processes for joining of dissimilar welded blanks. The prediction of local chemical composition in the weld formed between dissimilar steels in function of the welding parameters is essential because the dilution rate and the distribution of alloying elements in the melted zone determine the final tensile strength of the weld. The goal of the present study is to create and to…
Prosthetic modelling and simulation
2020
Abstract Modelling of physical systems can be divided into two categories: physical and mathematical modelling. Physical modelling is a process in which we construct tangible scale models that look very much like the real system. In the past century, consider the animal models that have significantly influenced the development of disease treatment and artificial joints. However, scale models require a great deal of time and resources to develop and there are limits to what can be learned from them. Mathematical or behavioural modelling is a more abstract system used for studying a research question that does not necessarily lend itself to physical modelling. In these models, the system is s…
