Vacuum-caps membranes' equilibrium state forms based on the energy criterion
(Primedia eLaunch, 2023) Vatrenko Oleksandr; Kyrylov Volodymyr; Gavva Oleksandr
The equation (26), obtained by solving the local energy effects equations, is a scope equation that characterizes and represents the energy transformations in the membrane body. It is experimentally found that the membrane additional deflection when operational state is significantly less than its initial deflection. The quoted calculation demonstrates the resulting scope equation's adequacy to the initially bent real metal plates in case of load counteracting the initial deflection, in particular for glass canning containers' metal caps membranes. The membrane energy levels diagrams obtained using equation (26) for characteristic equilibrium states are correct and agree with the Lagrange-Dirichlet theorem. Therefore, the equation (26) can be used in the industry manufacturing the canned food products metal packaging materials, as well as in the instrument building industry. The round elastic plate controlled stability loss computational mode has been build, checked and developed.
