WebAn elastomer is a polymer with viscoelasticity (i.e. both viscosity and elasticity) and with weak intermolecular forces, generally low Young's modulus (E) and high failure strain … WebThis wide range causes uncertainties when it comes to critical applications requiring accurate values. For instance, if the value of 0.5 is used as the Poisson’s ratio, it would lead to, e.g., an infinite bulk modulus. Often, the linear relationship of the Young’s Modulus to the Shear Modulus is used to determine Poisson’s ratio.
