Determination of buckling critical stresses for box-section short rod made of plasto-elastic material
JSC «NPO PM – Small Design Bureau»
Critical stresses are calculated from minimal conditions of system’s potential energy using Euler’s variational problems equations. End formulas for axial and eccentric compression are derived. Computation method is given. It is shown, that computational and experimental data for support brackets of “Cosmos-3M” launch vehicle constitute a match.
