Applications of Impact Dynamics to Assessment of Composite Erosion Resistance

Surface damage or material removal during particle target collision is the result of material response to the contact stresses. Energy dissipation under two bodies collision may be estimated by means of the coefficient of velocity restitution and friction. Approach of impact dynamic and experimental study of dynamic coefficients has been applied to clarify the composite material behaviour under conditions of solid particle erosion. It has been shown that the level of energy dissipation during application and value of dynamic coefficient of friction can be a good guide for material selection for the use in conditions of dynamic loading.Copyright © 2005 by ASME
