弹性模量：Elastic modulus is the unit of measurement of an object’s or substance’s resistance towards deformation elastically upon the application of stress. This is also known as the modulus of elasticity.In other words, elastic modulus is the slope of its stress-strain curve in the elastic...
Modulus of elasticityTensile strengthStress–strain curveMaterial characterization of low strength concrete has significant importance for structural/ seismic performance assessments of existing low-quality structures. The main objectives of this study are to characterize the compressive and tensile behaviors of...
The meaning of MODULUS OF ELASTICITY is the ratio of the stress in a body to the corresponding strain (as in bulk modulus, shear modulus, and Young's modulus) —called also coefficient of elasticity, elastic modulus.
Modulus of elasticity is the measure of stiffness properties of a material or structural element. It is generally used to measure the elastic resistance of an objected subjected to axial loading. It is taken as the slope of stress–strain curve in the elastic region. Modulus of elasticity of ...
This paper presents the yield stress σ y and the modulus of elasticity E of the soils subjected to repeated stress application. Unconfined and triaxial compression tests were conducted on the compacted specimens of silty loam, clay and three kinds of clay-sand mixture by means of stress control...
Stress-Strain Curve for Modulus of Elasticity of Concrete If you see these curves J – K and L. the J is the curve for aggregate – being the stiffest. K is for the concrete while L curve is for the cement. Now here to get the modulus of elasticity, just evaluate the slope of the...
Locked-in stress is a special stress objectively existing in the rock which has an important influence on the mechanical properties. However, there were few studies on the locked-in stress in rocks. ...

(Strain is dimensionless.) Thus Young’s modulus may be expressed mathematically as Young’s modulus = stress/strain = (FL0)/A(Ln − L0). This is a specific form of Hooke’s law of elasticity. The units of Young’s modulus in the English system are pounds per square inch (psi),...
