STUDYING SUPERCRITICAL DEFORMATIONS OF FLAT ELLIPSOIDAL PANELS OF CONSTANT THICKNESS
DOI: 10.17804/2410-9908.2022.4.081-089 An algorithm is developed for studying the stress-strain state of elastic thin-walled shell systems consisting of shells of revolution. Based on this algorithm, a computer program is written which allows one to determine the stress-strain parameters of shells in a wide range of geometric, physical, and force parameters. Supercritical deformations of flat ellipsoidal panels of constant thickness are studied.
