<br/><br/> The Design of Experiments (DOE)approach was used to build quantitative empirical models of the residual mechanical properties of crazed polycarbonate as functions of relative craze density, crazing stress, and strain rate. Crazing did not affect the yielding behavior of polycarbonate, but increasing tlhe strain rate increased the yield stress accordmg to the Eynng theory. The Eyrtng activation volume for yielding of crazed polycarbonate was measured to fall between reported values for conformational changes of a dilute solution of polycartonate chains and yielding of uncrazed polycarbonate. Also, with as little as 1
