Some questions relating to the strength of glass laminate

  • V. A. Kopnov
  • V. D. Protasov


The ultimate strength of glass laminate is investigated in the plane-stress case, in which the directions of the principal stresses do not coincide with the axes of anisotropy of the material and one of the principal stresses is equal to zero. The experimental data are compared with the results of calculations based on expressions describing the onset of the limiting state proposed in [1]. The agreement is satisfactory.
