Abstract
Способ испытания на статическую устойчивость тонких пластин, включающий закрепление образца в захватах, деформирование сжатием, фиксирование критической силы, отличающийся тем, что деформирование сжатием осуществляют как одноосное сжатие пластины при заданной постоянной скорости движения активного захвата («жесткое» нагружение), при этом проводят регистрацию формы равновесного состояния образца с помощью фотосъемки с заданным временным интервалом, строят диаграмму деформирования в координатах «прогиб пластины - время», имеющую два характерных линейных участка плоского и искривленного равновесных состояний, находят точку изменения формы равновесного состояния образца, определяющую критическую силу.The test method for the static stability of thin plates, including fixing the sample in the grips, compressive deformation, fixing a critical force, characterized in that compressive deformation is carried out as uniaxial compression of the plate at a given constant speed of the active capture movement ("hard" loading), while registering the shape of the equilibrium state of the sample using photography with a given time interval, build a deformation diagram in the coordinates of the "deflection of the plate - time", with two characteristic linear sections of flat and curved equilibrium states, find the point of change in the shape of the equilibrium state of the sample, which determines the critical force.
