WebThe formula of Young's modulus is: E = σ/ε where, E is the Young’s modulus σ is the stress and ε is the strain Other names include tensile modulus, elastic modulus, or modulus of elasticity. The physics behind young's modulus When a stretching force (tensile force) is applied to an object, it extends. Webshows the range of E-modulus of TPU and RTPU in comparison to other materials. The modulus of elasticity (E-modulus) is determined by tensile testing according to DIN EN ISO 527-1A, using a test specimen at a testing speed of 1 mm/min. The E-modulus is calculated from the initial slope of the stress-strain curve as ratio of stress to strain.
