The influence of the shell plating for background stresses in static deformation of truss Structures made of composites
The problem of taking into influence for constructive cutouts in the ribbed shell structures under static deformation. It is proposed two-level mathematical model to calculate the stress concentration coefficients based on the analytic solution of the idealized problem and obtaining the amendments by the full discrete model ribbed shell of composite materials. The influence of geometric characteristics of the uncompensated and reinforced cutouts, elastic moduli and the size of edging on the stress-strain state of shells. The practical significance of these results is to clarify the method for calculating stresses in a ribbed shell structures with constructive cutouts.
