'Young's Modulus' or modulus of elasticity is a measurement of the rate of change of strain as a function of stress. It represents the slope of the straight-line portion of a stress-strain curve. With respect to tensile testing, it may be referred to as Tensile Modulus. This method of testing is used to determine a sample's behaviour under an axial stretching load. Common tensile test results include elastic limit, tensile strength, yield point, yield strength, elongation, and Young's Modulus. Young's Modulus is reported commonly as N/mm² (lbs/in²), MPA (psi).

Young's Modulus testing can be carried out on a range of Lloyd Instruments  materials testing machines together with  NEXYGENPlus data analysis software when more comprehensive testing results are required.
