For material initially undamaged, the appropriate parameter expressing the tendency for cracks to be developed, and therefore strength to be lost, can be considered to be that for crack initiation. This has been expressed in terms of thermal stress resistance parameters.25,30,52,86-88 Kingery used the infinite slab symmetrically heated or cooled with a constant heat transfer coefficient to derive thermal shock fracture resistance parameters R, R and fusing the equations ...

The straight solid line - the consequence of equations (3.52) and (3.53) at — 0 -depicts the analytical result for the Rouse dynamics. The solid curves represents the displacement for a macromolecule of length M = 25Me (% = 0.04) with corresponding (according to relations (3.25) and (3.29)) values of parameters B = 429 and ijj = 8.27 and the values of parameters of local anisotropy ae = 0 and ae = 0.3. For the isotropic situation (ae = 0), the curve can be calculated analytically according to equation (5.5), but for the parameter of local anisotropy ae = 0.3, the displacement ought to be calculated numerically. Internal resistance (parameters E and cq) does not affect mobility of macromolecular coil. Adapted from Pokrovskii (2006).
