SUMMARYIn this paper we discuss the discrepancies between results reported in the literature in the context of dynamics of shell structure composed of three intersecting plates. The shell structure is subjected to a system of spatially uniformly distributed dead loads of prescribed time variation. Once the forces die out, the structure experiences free motion. The comparison of reported solutions from the literature shows that the total energy in free motion has different values, despite the fact that the same material, geometry and loads have been used. The aim of study is to address the issue by referring own results to that known from the literature. The example discussed here belongs to the tumbling flexible structures. In literature a spaghetti problem was first modeled and analyzed in [1] and then in [2-4] using rod formulation. These studies gave an impulse for analyzing this type of problems using various rod and shell formulations. The ultimate goal and the culmination of the studies by Simo and Vu-Quoc on flying flexible structures, with application to satellite dynamics, can be found in [5].The example discussed here, see Figure 1, is concerned with motion (without gravity loads) of irregular shell structure subjected to spatial system of uniformly distributed dead loads of given time variation. After the driving loads die out the structure experiences free motion where, by definition, the total energy, linear momentum vector and angular momentum vector of the structure must remain constant. The problem has been studied, among others, in [6][7][8]; yet in the latter reference the load was defined differently than in the two former papers. Consequently, the results from [8] cannot be discussed directly here. The comparison of results reported in [6,7] indicates significant discrepancies between computed total energy of the structure. The reported values are respectively: approximately 70 and approximately 20. What makes the matter interesting is that in both papers, the same geometrical, material and load parameters are reported to have been used.That the structure is composed of orthogonally intersecting plates and experiences unlimited rotations and translations makes the example a challenging task for every shell theory incorporating the sixth degree of freedom (DOF), the finite elements elaborated within that theory and temporal
