ABSTRACT:
A method and apparatus wherein a material or object to be tested is placed on a base support. A stopper assembly having a stopper tip on one end in contact with the test material or object, and a washer on the opposite end attached to a rod. A projectile is propelled with a selected level of force along the rod and impacts the washer, which transmits the force of impact through the stopper tip to the test material or object. The level of propelling force, the mass of the projectile, the construction of the stopper assembly and the location of impact on the test material or object may be precisely adjusted to simulate real-life impacts.
