Abstract
IT has been known for many years that hydrostatic pressure increases the ductility of metals1 and that metals which are brittle in tension at atmospheric pressure become ductile at higher pressures2. Although the effects of hydrostatic pressure on mechanical properties have been studied for some non-metallic materials1, there appears to be no record of similar studies on brittle glassy polymers. Some preliminary tensile tests under hydrostatic pressure have, therefore, been carried out on polystyrene at the National Engineering Laboratory using the method described in ref. 3.
