The impact of aging time, stress magnitude and temperature on the crazing response of polystyrene and a styrene-acrylonitrile copolymer subjected to equi-biaxial stress conditions was studied. Several models that described the craze initiation of the polymers were discussed under equibiaxial stress and uniaxial strain test conditions. Physical aging decreased the strain at crazing and increased the time for the polymer to craze.
