Effect of Asymmetric Heat Transfer on Glass Deformations
Keywords:Glass tempering, bending, Asymmetric temperature field
During tempering or other heat treatment processes an uneven temperature field or even an asymmetric temperature field can be created in glass. In an asymmetric case glass can bend depending on the degree of temperature difference. With a known temperature field thermal strains, stress field, and deformations can be calculated. In the paper the theory governing the stress field and deformations is presented. A viscoelastic behavior with the structural relaxation of glass is taken into account.
