| Abstract: | Single crazes in transparent glassy thermoplastics are measured by means of optical interferometry. Applying numerical or analytical methods to measured creaze shapes, also their micromechanics has been evaluated. These data can be transferred to rubber-modified species of the respective thermoplastics to predict craze-governed toughening. Such predictions can be verified by comparison with results of electron microscopic investigations.Dedicated to Professor Hans-Henning Kausch on the occasion of his 60th birthday. |
