Mechanical properties of solids are key to predicting or explaining their behaviours in response to external force and stress. Such properties enable a solid material to react differently to various kinds of loads e.g. tension, compression, shear, or torsion. ... Brittleness: When a material breaks rather than stretches under tension.

A fracture is the separation of an object or material into two or more pieces under the action of stress. Engineers need to understand fracture mechanisms. There are fractures (e.g. brittle fracture), which occur under specific conditions without warning and can cause major damage to materials. Brittle fracture occurs sudden…

Estimating brittleness from frictional strength (Eq. 7=B Mohr) yields relatively high values for carbonates, sandstone and granite, comparable to those of ALM and BAR shales (Fig. 7 b). In contrast, Posidonia shales are more ductile with slightly decreasing index values with increasing temperature, comparable to the effect of bedding orientation.

Properties of solid. 1. They have fixed shape size and volume. 2. They are incompressible and inflexible. 3. The particles constituting a solid may be atoms (e.g, in metal), ions (e.g, in NaCl), or molecules (e.r, dry ice). These occupy a fixed position and only oscillate about their mean position. 4. Molecules have a short intermolecular distance.
