WebYoung's modulus is the slope of the linear part of the stress-strain curve for a material under tension or compression. Young's modulus , the Young modulus, or the modulus of elasticity in tension or compression (i.e., negative tension), is a mechanical property that measures the tensile or compressive stiffness of a solid material when the ... WebDefinition. The elastic modulus of an object is defined as the slope of its stress–strain curve in the elastic deformation region: A stiffer material will have a higher elastic modulus. An elastic modulus has the form: = where stress is the force causing the deformation divided by the area to which the force is applied and strain is the ratio of the change in some …
