It has a Mohs hardness of 6.5 and a specific gravity of 2.9 . It has a brittle fracture and no cleavage.
22.
Mixing polymers is another method of increasing strength, particularly with materials that show crazing preceding brittle fracture such as atactic polystyrene ( APS ).
23.
If experiments are performed at a higher strain rate, more dislocation shielding is required to prevent brittle fracture, and the transition temperature is raised.
24.
The sinking of in 1912 from an iceberg collision is widely reported to have been due to brittle fracture of the hull's steel plates.
25.
An important presumption is that the internal deformation of the wedge takes place by frictional sliding or brittle fracturing and is therefore independent of temperature.
26.
In theory, any rock there should have the consistency of putty, ruling out the brittle fracture and frictional sliding found in faults near the surface.
27.
The dyke swarm could extend for such a large area because of the pre-existing basement brittle fracture networks, instead of stress formed by the plate movement.
28.
Although CFRPs with epoxy have high strength and elastic modulus, the brittle fracture mechanics present unique challenges to engineers in failure detection since failure occurs catastrophically.
29.
The classical approach to brittle fracture in the late 1940s had been developed in the early 1920s, following the work of A . A . Griffith.
30.
Further trials are necessary, as analysis has shown that the failure modes for the munition casings involved a mixture of brittle fracture, plastic deformation and shearing.
