Information × Registration Number 0215U008046, 0114U002164 , R & D reports Title Vibration and stability of smooth and discrete stiffened shells elements under static and impulse loadings. popup.stage_title Head Lygovyy Petro Zakharovich, Registration Date 05-11-2015 Organization S.P.Timoshenko Institute of Mechanics popup.description2 The problem of determination the minimal vibration frequencies of the shells with deflections, stiffened cylindrical shells on elastic foundation is considered. The structurally orthotropic theory at the most approximate to the theory of discrete model of stiffened shells is used. The formula for determination the minimal vibration frequencies is derived and calculation technique is obtained.
