I'm joining a flange and a cap using 9 bolts with a steel gasket placed in a 'o' ring. To ensure that the joint is leak proof, I need to calculate the load distribution in the area between two bolts for a given torque in the bolt[please refer to the figure, where the lines indicate the area where I need the load distribution]. Whether the whole area is uniformly loaded or not. Can some one please help me on how to approach this calculation???
