Stress concentrations leading to brittle failure can be minute surface or interior cracks (microcracks) or internal pores, which are virtually impossible to eliminate or control. Plane-strain fracture toughness ( K Ic ) values for ceramic materials are much...

... applications. While metals plastically deform due to the high mobility of dislocations (i.e., slip), ceramics do not exhibit plastic deformation at room temperature and are prone to catastrophic failure under mechanical or thermal loading. They have a very low tolerance to cracklike defects, which can result...

.... Pure magnesium has a melting point of 650 °C (1202 °F) and a hexagonal close-packed (hcp) crystalline structure. Because the hcp structure restricts slip to the basal planes, magnesium is difficult to plastically deform at room temperature; that is, the work-hardening rate at room temperature is high...

... of beryllium is low compared with that of most other metals. Beryllium has a hexagonal close-packed crystal structure; thus, there are relatively few slip planes, and plastic deformation is limited. For this reason, all beryllium products should be formed at elevated temperatures (generally 540 to...

..., if the crack is interlaminar or between the plies, the fibers are of no help in preventing crack propagation. One way of reducing crack propagation is to use second-phase elastomers. Discrete rubber particles help to blunt crack growth by promoting greater plastic flow at the crack tip, as shown in...
