WebNormal stress is subdivided into compression, when the stresses are squeezing a rock, and tension, when stress is pulling it apart. Rocks … WebWhen rock experiences large amounts of shear stress and breaks with rapid, brittle deformation, energy is released in the form of seismic waves, commonly known as an earthquake. 9.1: Stress and Strain. Stress is the force exerted per unit area and strain is the physical change that results in response to that force. WebThey found that the material under tension and shear loading shows a brittle, linear elastic behaviour. Only several isolated shear bands can lead to a macroscopic deformation.
