Analysis of stress-strain state of multi-wave shell on parabolic trapezoidal plan

The paper presents the calculation of stress-strain state of shell with carved middle surface (Krivoshapko and Ivanov in Encyclopedia of analytical surfaces. Springer International Publishing Switzerland, 752p, 2015 [1], Ivanov and Krivoshapko in Analytical methods of analyses of shells of non canonic form. RUDN, Moscow, 542p, 2010 [2], Ivanov and Rynkovskaya in MATEC web of conferences 95, 5p, 2017 [3]) with horizontal parabolic curve as directrix and multi-wave sine curve with axis in the plane of parabola as generatrix. We obtain the multi-wave parabolic sine shell on a curved trapezoidal plan (Fig. 1). There is a comparative calculation of two shells with different amplitudes of the sine generatrix—1 m and 0.5 directrix is a quadratic parabola— (Formula presented). © Springer Nature Switzerland AG 2020.
