where E is the Young's Modulus and υis the Poisson's ratio. Poisson's ratio varies between 0.2 and 0.3 for rocks. A principal stress component σ i produces a strain σ I /E in the same direction and strains (-υ.σ i / E) in orthogonal directions. Elastic behaviour of an isotropic material can be characterized

Basalt continuous fibers are produced from basalt rock using single-component raw material by drawing and winding fibers from the melt. The main features of basalt fibers include high strength and high modulus with excellent shock resistance; they are a low-cost alternative and can replace carbon fiber in some applications.

Rock - Rock - Stress-strain relationships: The deformation of materials is characterized by stress-strain relations. For elastic-behaviour materials, the strain is proportional to the load (i.e., the applied stress). The strain is immediate with stress and is reversible (recoverable) up to the yield point stress, beyond which permanent strain results.

At any stress level in region AB, the rock will follow a path essentially parallel to AB upon unloading and reloading. In that domain, the rock sample can be modeled as a spring. If the rock is isotropic, two elastic constants can be introduced to describe its deformability: the Young's modulus, E, and the Poisson' s ratio, <, with and
