STUDY OF EFFECT OF CIRCULAR HOLE IN PLATE, ON STRESS CONCENTRATION JJ Technical Solutions www.mechieprojects.com
AIM To study the stresses in flat plate with circular hole, for different pressure loads (P=50 MPa to 450 MPa) To study the effect of increase in pressure on the max. stresses developed. To study the stress profile across the circular hole, through the plate width. To tabulate and plot the max. stress generated in the flat plate with circular hole for different pressure loads.

Results and Discussions The max. stresses generated due to various pressure loads on the flat plate configuration are: The max. stress generated is a linear function of Pr. Load. The stress distribution across the width of the plate is plotted The stress distribution across the width of the plate for different Pr. Loads are plotted and studied. The stress distribution around the hole is studied. Sl.No. Pressure (MPa) Max. Stress (MPa) 1 50 159 2 150 477 3 250 795 4 350 1113 5 450 1431
