FRACTURE OF LAMINATED RECTANGULAR BAR AFTER BUCKLING

FRACTURE OF LAMINATED RECTANGULAR BAR AFTER BUCKLING

The delamination of composite constructional elements is determined by normal stresses and shear stresses. The non-linear strength criterion is suggested by the authors in case of complex state of stress. Fracture of laminate bar after buckling is described by mixed fracture spreading regularities....

Zusammenfassung:The delamination of composite constructional elements is determined by normal stresses and shear stresses. The non-linear strength criterion is suggested by the authors in case of complex state of stress. Fracture of laminate bar after buckling is described by mixed fracture spreading regularities. Dependence of fracture energy on mechanical characteristics of the layers and shear resistance of the interlayer is presented. The obtained theoretical values are based on experimental investigation of glass plastic.
