WebInitial modulus. Young’s modulus or the initial modulus (IM) is a measure of the amount of deformation that is caused by a small stress. Materials with a high modulus, often called stiff or hard materials, deform or deflect very little in the presence of a stress. Materials with a low modulus, often called soft materials, deflect significantly. 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.
