Setting up a theory of stability of fibrous and laminated composites

The results obtained in setting up a theory of stability of fibrous and laminated composites in the case where the plane Π is in an arbitrary position are analyzed. The plane Π is formed by the points of a buckling mode that have equal phases relative to the line of compression. This theory follows from the linearized three-dimensional theory of stability of deformable bodies and is used to determine the critical compressive load and the associated position of the plane Π. Numerical examples are presented. A brief historical sketch is given
