Abstract The strength and elasticity of layers of polyurethane foam with cylindrical cavities have been investigated on the interval of variation of the specific weight of the foam from ρ0 = 0.2 to ρ0 = 0.7 gf/cm3. A correlation has been established between the proportionality limit in compression along the channel axes and the modulus of elasticity of a cylindrical tube of foam with a radially restrained outer surface taken as a model of a layer with cylindrical cavities. The experimental results are compared with the theory of elastic compression of tubes with free and restrained ends.
