ANALYSIS OF BOX-LIKE SHELLS OF RECTANGULAR CROSS-SECTION

A method of analysing box-like shells, based on reducing the problem to the problem of the combined planar and flexural states of a plate with a defect, for which methods of solution are given in /1/, is proposed (the defect is understood to be a line for which jumps in the force of displacement occur when it is crossed). It is shown that for small thicknesses the solution of the problem of the state of stress of a box-like shell reduces to the sequential solution of two problems (flextural and planar), to within terms of a higher order of smallness. The results of calculating the bending moments and stress in the shell are represented in the form of graphs and tables.
