KINEMATIC MODEL OF REFINED THEORY AND EXACT ANALYTICAL SOLUTIONS OF STATIC AND BUCKLING PROBLEMS OF STRUCTURALLY-ANISOTROPIC COMPOSITE PANELS OF AIRCRAFT
L.M. Gavva, Moscow Aviation Institute (NRU) , Russia
New mathematical model relations for the stress-strain state and buckling investigation of structurally-anisotropic aircraft panels made from composite materials are presented. The refined theory of thin-walled elastic ribs is used without the hypothesis of the zero shear deformation for the reinforcing elements. Aircraft composite structure design in the field of production technology is proposed. Exact analytical solutions for edge problems are considered according to the general treatment of physical boundary conditions.
