 The shape parameter for 4 mm and 8 mm thickness glass is 8.537 and 9.11 respectively indicating no significant changes in scatter of fracture stress from its median fracture stress value for different thickness of the glass specimen.  The cumulative experiment probability of fracture strength of glass follows a Weibull model.  The fracture strength of the glass reduces from 46 MPa to 40 MPa with the increase in thickness from 4 mm to 8 mm respectively indicating the decrease in fracture stress with increasing thickness.
