Abstract:

Based on vacuum flat glass by a laboratory sample preparation， the residual stress field

of seal edge of vacuum flat glass was researched by the electric measuring， it successfully tested

the distribution of residual stress field of seal edge. Residual stress field of seal edge of vacuum

flat glass was analyzed by numerical analysis method. By this method， the law of the stress

distribution was obtained. The theoretical calculation results were basically consistent with the

experimental results. It was explored that the linear expansion coefficient of seal edge having an

influence on the residual stress of vacuum glass， and analyzed the stress coupling of seal edge

having an influence on the residual stress of vacuum glass too. Using the residual stress as the

basic parameters of assessing the failure of vacuum glass， to reveal the relationship between the

residual stress intensity and elasticity modulus， and create the new failure calculation method

based on the residual stress of vacuum flat glass. The contents of above mentioned study provided a

theoretical basis for the allowable analysis of the seal edge residual stress of vacuum glass.
