How to measure shear strength
WebShear strains measure the relative parallel movement of one reference plane for another. The symbol for shear strain is usually the lowercase Greek symbol gamma (γ ). Deformation The deformation measures how much an object deforms from its original dimensions or size in a given direction. Web10 feb. 2024 · Undrained shear strength is a measure of the maximum shear stress that a soil can withstand without experiencing any change in its volume in undrained condition. It is defined as the maximum shear stress that can be developed in a soil sample without allowing the soil to drain, which means the water pressure within the soil remains constant.
