Effect of Hole on Stresses of a Flat Plate

  1. 1. STUDY OF EFFECT OF CIRCULAR HOLE IN PLATE, ON STRESS CONCENTRATION JJ Technical Solutions www.mechieprojects.com
  2. 2. 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.

  21. 21. 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
