Simulation of the Cold Spray Particle Deposition Process in Abaqus by using CEL method

In recent years, a significant number of studies have been dedicated to the modeling of impact dynamics. For very low-speed impact, such as in the shot peening metal working process, the semi-analytical method can be used for the modeling of both thick (half-space assumption) and thin (finite-depth) structures.In the case of higher-speed impact, such as in the cold spray particle deposition process, three explicit finite element analysis codes,ABAQUS, LS-DYNA have been used to investigate the whole deformation history of materials. The cold gas dynamic spray process, often called simply “cold spray,” was initially developed in the mid-1980s. In this deposition process, the spray particles (1–۵۰ micro meter) are accelerated to a high velocity (300–۱۲۰۰ m/s) by a high-speed gas flow so as to form a dense and high-quality coating thanks to the plastic deformation of the particles impinged upon the solid surface of the substrate.Due to the presence of highly transient nonlinear and dynamic phenomena with contact, the interactions between the particles
and the substrate during cold spray deposition are very difficult to analyze experimentally. Micro structural and micro analytical studies offer little help in identifying the relative contributions of the various bonding mechanisms. Therefore, numerical simulation of the particle/substrate interaction has played a major role in understanding the cold spray bonding mechanism. So we shall start with a brief description of the fundamental concepts of the numerical methods used in this study.

In this simulation three dimensional CEL analysis has been used. The aluminium material for target and spray is consider with Johnson-Cook model. Dynamic Temp explicit is appropriate for this type of analysis.You can see some figures of this simulation at below
