WebRocks and minerals Sonelastic® Systems are able to measure the elastic moduli and damping of rocks and minerals, the main applications are: - Classification; - Quality control; - Geological soundings; - Evaluation of thermochemical damage; - Characterization of mechanical properties for drilling and mining optimization. Traceable calibration WebModulus is defined as being the slope of the straight-line portion of a stress (σ) strain (ε) curve. Focusing on the elastic region, if the slope is taken between two stress-strain points, the modulus is the change in stress divided by the change in strain.

Results from the analysis demonstrate ... WebModulus of elasticity (or also referred to as Young’s modulus) is the ratio of stress to strain in elastic range of deformation. For typical metals, modulus of elasticity is in the range between 45 GPa (6.5 x 10 6 psi) to 407 GPa (59 x 10 6 psi). Modulus of elasticity is also a measure of material's stiffness or resistance to elastic deformation. features of places geography stage 1
