Abstract

A mathematical model of deformation and a method for calculating the influence of parameters on residual technological strain, tangential displacements, and the deflection function of a single curvature composite shell reinforced by stringers are presented. The parameters include the physical and mechanical characteristics of the material, difference between the curing and operating temperatures as well as the geometry and temperature strains of the tooling.
