TANGENTIAL STRESS FACTOR COMPUTATION IN POINT MOUNTED STRUCTURAL GLASS

The main objective in this study is to compute the stress factors when the effect of countersinking a hole comes into play in comparison with the stress factors computed for a cylindrical straight bolt hole in accordance with DIN 18008-3. FEM analysis using 3-D volume elements were done with the commercially available software Abaqus. The study was carried out for various dimensional parameters of point mounted glass. This study has also carried out parametric sensitivity analysis for a single counter-sunk bolt hole and a double counter-sunk bolt to compute the increase in the tangential stress factor values when changing over from a straight cylindrical hole to a countersunk and a double countersunk hole. It was found that the stress factors increase when the hole is countersunk.
