On the basis of the data of craze behaviour under static tension, the deformation curves followed by continuous initiation and growth of crazes are plotted for a variety of testing conditions, such as constant stress, constant strain-rate and constant strain tensions applying the Johnston-Gilman theory for dislocations. Experimentally determined values of the density and growth rate of crazes, which are regulated in accordance with a simple rate theory, are used for the calculations. Comparison of the theory with the experimental results is favourable except for the results of high strain-rate tension and stress relaxation. The application of the dislocation analogue approach to the craze deformation kinetics was found to be valuable.
