A method for determining the Young’s modulus of polymeric materials from deformation diagrams of thin-walled circular cylindrical shells in compression in the region of geometrical nonlinearity has been elaborated. A numerical solution is found by the finite-element method (ANSYS.) The existence of a unified deformation diagram in generalized coordinates is established, from which the flexural Young’s modulus is determined. To validate the method, the Young’s modulus of specimens was found experimentally.
