Сравнительный анализ двух подходов к исследованию параметрических колебаний ортотропных пластин сложной формы

Abstract

Parametric vibrations of the orthotropic plates with complex form and various boundary condi­tions are studied by two approaches. The first method uses the movement equations in terms of dis­placements; the second approach is based on using the equations in mixed form. The results obtained by the presented algorithms are compared for T-plate
