Single crazes in transparent glassy thermoplastics are measured by means of optical interferometry. Applying numerical or analytical methods to measured craze shapes also their micromechanics has been evaluated. These data can be transfered to rubber modified species of the respective thermoplastics to predict craze govemed toughening. Such predictions can be verified by comparison with results of electron microscopic investigations.
