In this tutorial, the Simulation deposition behavior of multi-particle impact in the cold spraying process in Abaqus has been investigated. The aluminum particles are modeled as three-dimensional solid parts. The aluminum target also is modeled as a three-dimensional solid part. You can see a figure of the assembled parts
In the practical cold-spraying process, several particles impact onto a substrate and then form a coating. To study the deformation behavior and multi-particle interactions, single-particle, two-particle, and three-particle impacts were simulated using Abaqus software. A contact model that accounts for interfacial cohesion and thermal conduction is developed to investigate the influence of bonding on the final residual stresses build-up in cold spray. The impact of particles on a flat substrate is simulated in a Lagrangian reference frame by using the commercially available FE analysis software ABAQUS/Explicit. The Lagrangian method is used as it provides a unique way to model the interface contact interactions for the particle bonding
The aluminum material with elastic-plastic behavior is selected. The dynamic explicit step and proper interaction with interaction property are considered. The proper boundary and mesh are assigned to parts
After the simulation, all results such as stress, strain, deposition of particles, temperature, and others are available. You can see some figures for the results below
