Abstract
The mathematical model relations for buckling investigation of structurally-anisotropic panels made of composite materials are presented. The mathematical model of stiffening rib being torsioned under one-side contact with the skin is refined. One takes into account the influence of panel production technology: residual thermal stresses and reinforcing fibers preliminary tension. The resolved eight order equation and natural boundary conditions are obtained with variation Lagrange method. Computer program is developed using operating MATLAB system. The influence of the structure parameters on the level of critical buckling forces for bending form has analyzed.
