Engineering Formula

t = √(β × P × a × b × SF / f)

t = Thickness (mm)

β = Aspect ratio coefficient

P = Pressure (PSI)

a, b = Panel dimensions

SF = Safety factor

f = Allowable stress (PSI)

Minimum Required Thickness

8mm

Calculated: 7.49 mm

Calculation Successful

Standard thickness meets safety requirements

Panel Dimensions

Safety Factor

5.0×

Maximum Safe Pressure

1.14 bar

Glass thickness 8mm can safely handle up to 1.14 bar

Design Recommendation

Always verify calculations with material certifications and apply appropriate safety factors for your specific application. Consider environmental factors, edge support conditions, and manufacturing tolerances when finalizing glass specifications.
