The dynamic compression testing of solids by the method of the split Hopkinson pressure bar

The mechanical behaviour of some metals (annealed copper, aluminium, magnesium, zinc and brass) and polymers (polymethylmethacrylate, polyethylene, polyvinyl chloride, polytetrafluoroethylene, polycaprolactam and a filled rubber) has been investigated experimentally for compressive loading cycles of 30 ∽sec duration. Cylindrical specimens, of comparable length and diameter, were sandwiched between two (elastic) rods and deformed under the action...
