【Abstract】

<正>Collisions between multibody systems are irreversible processes which cause loss of internal energy by a stress wave that propagates in the impacting bodies away from the region of impact.A coefficient of restitution relating to approach velocity is introduced to denote the losses of translational kinetic energy.In the paper,the relationship between normalized oscillating frequency and normalized approach velocity has been calculated.The parameter□involved in internal energy Iosses has been obtained from an integrate equation.As a result,the internal energy losses caused by elastic stress waves and the contact duration in metals can be calculated numerically for the collision between circular cylinder and half plane.The metals include Aluminum alloys,Steel-mild 1020,Steel-stainless austenitic 304,Tungsten alloys,Copper alloys,Nickel alloys and Titanium alloys.
