Simulation And Analysis Of The Stress In Flat Glass Based On ANSYS

The internal stress is very complex, when glass changes into solid-state from liquid.The analysis of the factors which affect the temporary and permanent stress is work toreduce the burst of glass in modeling process and improve the stress’distribution in glass.It helps to improve efficiency and quality. The stress’distribution have been simulatedunder Free and constraint boundaries conditions in this essay, which helps to find themaximum stress at the glass location where is most likely to burst.Firstly, the two-dimensional glass model has been established based on ANSYS,through modeling and parameter setting. Setting the glass annealing progress, middle andsurface layers’stress have been simulated. Processing the data with MATLAB, The stressvariation changing with the temperature difference between middle and surface layers, hasbeen given.Secondly, by changing the annealing rates of B area, the permanent stress at differentrates has been obtained. Processing the data with MATLAB, the relationship betweenpermanent stress and B area annealing rates is gotten, which is then compared with thetheoretical calculations. Also the same is C area.Finally, the heat models of free and constraints boundaries have been established.X-direction and Y-directions stress, changing with the heating process, have been analyzed.The nature of stress in the X-direction, under the free and constraint boundaries wascompared. Also, the X-direction stress changing with location of the glass is gotten. Thenature of stress in the Y-direction, under the free and constraint boundaries was alsocompared. The Y-direction stress changing with the location of the glass is gotten, too.
