The purpose of this research is to obtain a better understanding of the stress state in ductile substrate due to impact of hard particles. Impact dynamic finite element analyses were performed using a nonlinear transient finite element code. In this phase of the research, only rounded particle is considered. Other considerations include impact angles and velocities. Resulting stress state at various locations of the impact region was studied. Results provide insights into the mechanisms for erosion wear and are used to explain erosion wear behavior in ductile substrate. A wear relation was developed to include the fatigue wear mechanism.
