## Abstract The dynamic fatigue method was used to obtain subcritical crack growth parameters __n__ and __A__ for a commercial feldspathic dental porcelain and for a lanthanumβglassβinfiltrated alumina glass ceramic. Five stress rates __d__Ο/__dt__ ranging from 50 to 0.01 MPa s^β1^ were applied. Th
Carboxyl-terminated polybutadiene ( CTPB ) was subjected to temperature and humidity aging in order to estimate its useful lifetime as a solid propellant binder. CTPB samples were temperature aged from 1 week to 7 months at various temperatures ranging from 50 to 100Β°C. At various stages of temperat
