- Abstract
- The mathematical model relations for the buckling problem investigation of structurally-anisotropic composite panels are proposed in view of the variable pre-critical stress-strain state. The resolved eight order equation is designed with the refined mathematical model of a stiffening rib being torsioned under one-sided contact with the skin. One considers the residual thermal stresses and the preliminary tension of the reinforcing fibers with respect to panel production technology. The influence of the structure parameters on the level of critical buckling forces for bending and for torsion modes has analyzed. The results of testing series are presented.
