Whenever the random accumulation of defects in one site has grown to such a size that subsequent fractures will preferentially occur at that site, one has reached the end of the phase of fracture initiation and the beginning of (thermal) crack growth... [Pg.64]

Plastics are susceptible to brittle crack-growth fractures as a result of cyclic stresses in much the same way as metals. In addition, because of their high damping and low thermal conductivity, plastics are prone to thermal softening if the cyclic stress or cyclic rate is high. Examples of the TPs with the best fatigue resistance include PP and ethylene-propylene copolymers. [Pg.82]

The properties of glassy polymers such as density, thermal expansion, and small-strain deformation are mainly determined by the van der Waals interaction of adjacent molecular segments. On the other hand, crack growth depends on the length of the molecular strands in the network as is deduced from the fracture experiments. [Pg.346]

Ogawa et al. [100,101] reported the use of various EPDM polymers in blends with NR in black sidewall formulations. Laboratory testing showed improved resistance to crack growth and thermal aging. [Pg.483]

Isobutylene has had a tremendous increased production in the last few years because of the dynamic growth of the gasoline additive MTBE. About two thirds of it is made from isobutane by dehydrogenation in thermal cracking. [Pg.127]

Alternative approaches, termed indentation thermal shock tests , with pre-cracks of known sizes have been used by several authors to assess thermal shock damage in monolithic ceramics. Knoop (Hasselmann et al., 1978 Faber etal, 1981) or Vickers (Gong etal., 1992 Osterstock, 1993 Andersson and Rowcliffe, 1996 Tancret and Osterstock, 1997 Collin and Rowcliffe, 1999, 2000 Lee et al., 2002) indentations were made on rectangular bars, which were then heated to pre-determined temperatures and quenched into water. Crack extensions from the indentations were measured as a function of quench temperature differential, and the critical temperature for spontaneous crack growth (failure) was determined for the material. Fracture mechanics analyses, which took into account measured resistance-curve (7 -curve) functions, were then used to account for the data trends. [Pg.409]
