Review article

The article substantiates the relevance of rubber replacement for polyurethane elastomers (resilient materials). A loading device for studying the deformability of polyurethane sample is described. The phenomenon associated with the interaction of polyurethane massif with support plates or the so-called edge effect is highlighted. The paper presents a relationship for calculating the modulus of elasticity of polyurethane elastomeric array, depending on the conditions of contacting at the ends and the geometry of the array.
