Hi everyone,

I would want to ask something about Glass Tempering Process Which ı read the article about this issue. How can ı calculate the partial  fictive temperature. 

 I know the fictive temperature =real temperature till to Tg, but ı want to calculate coorelation about Tf and structural relaxation times,weigthing factor also partial fictive temperature. ı just know the initial fictive temperature.

That's the article that I wanna learn. There is bulk and shear prony series Also relaxation times and structural part and I added the other properties depended to temperature.

Effect of glass temperature before cooling and cooling rate

on residual stresses in tempering

I created the tension stress, center of the glass and compression at the surface. That's phonomena  tempered of glass.

That’s the engineering data which ı created.I estimated the partial fictive temperature for just check what’s gonna happen

Anyone for help?
