Обратная задача для шарнирно-опертой пластины с дополнительной упругой опорой при нестационарном нагружении

Mechanical system consists of hingedly supported medium-thickness rectangular plate with additionalconcentrated elastic support. The nonstationary concentrated load, which initiates vibration, is acting onthe plate. The inverse problem of an unknown loading identification is solving, when plate’s pointsdeflections in time are known. Also the possibility of elastic support stiffness determination is considering.
