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. WebYoung’s modulus (modulus of elasticity) is established by conducting the tensile test in accordance with DIN 53504 on an S1 specimen defined by DIN EN ISO 3167, employing a … how many singers has black sabbath had
