On the nature and magnitude of deformation affects not only the magnitude of loading, but also the rate of load application

The mechanical properties of building materials
The mechanical properties reflect the ability of bodies (material) to resist the force (from mechanical stresses), heat, shrink, or other stresses without breaking the established structure. In turn, energized understood measure of the intensity of internal forces generated by the action of loads, temperature changes and other factors or causes. Virtually stress is defined as the inner force per unit area, with a mean force of the inner strength of the particles located on one side of the site, the particles that are on the other side of this site. Usually determined by calculation the normal (perpendicular to the plane) and shear stress expressed in MPa in SI.

The mechanical properties are separated by the deformation and strength.

Characterize the deformation properties of a material’s ability to change the shape or size without any variation in the magnitude of its mass.

Deformation – changes in volume or shape of solid or plastic body without weight change. The principal types of deformation – tension, compression, shear, torsion and bending. All of them may be reversible or Read the rest of this entry »
