摘      要：Based on the analysis of different theory for glass tempering process,the“structural theorywith stress relaxation and structural relaxation effects was selected to investigate the tempering of flat glass *** geometrical model with small size and non-homogeneous mesh were considered to build the finite element models according to the characteristics of stress *** tempering process of flat glass with12 mm thickness was calculated with the verified finite element *** transient and permanent stress of the central area,edge and corner end of the flat glass are obtained and *** the calculation results of basic case,the transient tensile stress at the upper surface of the central area,the center point of edge,the edge of edge,the edge of corner were 14.30,18.94,40.76 and 34.75 MPa,*** transient tensile stress at these points were dangerous to promote the glass to break during the *** addition,the point at the diagonal line of symmetry plane in the thickness direction,which is 14 mm from corner,has the maximum permanent tensile stress about 70.01 MPa in the flat glass after ***,it is indicated that the corner is the weakest region in the tempered glass.
