A: Glass grows by the side of short edge: 1.000m
B: Glass grows by the side of long side: 1.440m
T: Vitreous ply: 5.0mm
ψ: Vitreous board face is crossed in curve coefficient, Grow by the edge thanA/bCheck
Watch5.4.1: 0.075
σW: Vitreous place suffers stress:
σW=6× ψ ×Qb×A^2×1000/(1.25×T)^2
=6×0.075×1.801×1.000^2×1000/(1.25×5.0)^2
=20.853N/mm^2
20.853N/mm^2≤ ｆG=84.000N/mm^2
Vitreous intensity is contented!
4.Vitreous temperature stress is calculated:
School nucleus basis: σMax≤≤σ] =58.800N/mm^2
