Evaluation of Geometric Stress Concentration Factor
Plate Subject to Tension With Hole in Centre
This applet determines the theoretical stress concentration factor for a rectangular plate subject to tension (in a horizontal direction in the applet below) with a central hole. The ratio of the hole diameter / plate width should not exceed 0.5.
Enter the plate width and hole radius in mm and click on the 'Calculate' button.
This stress concentration factor is for use with the average stress calculated on the net reduced cross section area, ie:
These calculations are based on information contained in "Roark's Formulas for Stress and Strain", 6th Ed. McGraw Hill, 1989 and also "Stress Concentration Factors", by R E Peterson, John Wiley and Sons, 1974. Both these publications contain information relating to a large number of configurations.
