Beam bending

It deals with a method for the determination of the viscous behaviour of glass especially in range of transformation.

Bar-shaped samples with defined dimensions are loaded by three-point bending. The deformation behaviour und influence of temperature delivers data for the calculation of Annealing and Strain Point.

(Samples: massive glass pieces, 30 x 20 x 4 mm or bigger respectively bar-shaped pieces from 5 mm)
