Strength of laminated cylindrical shells upon nonproportional loading

A general approach to the construction of a fracture model of multielement systems has been proposed.
A mathematical model of the fracture of a laminated cylindrical shell has been developed on the basis of the proposed approach, and the effect of the loading path and the number of layers in the shell (scaling effect) on the form of the strength diagram has been investigated.
The effect on the form of the strength diagram of statistical effects associated with the omission from the discussion of shells which lose competence during preliminary loading has been shown; a type of scaling effect which qualitatively affects the form of the strength diagram has been detected along with the known scaling effect; the effect of the loading path on the form of the strength diagrams has been shown.
