### Stress in Flat Plate due to Different Diameter Holes

1. 1. STRESS IN A FLAT PLATE DUE TO CIRCULAR HOLE JJ TECHNICAL SOLUTIONS WWW.MECHIEPROJECTS.COM
2. 2. AIM • To study the stresses in flat plate with circular hole, for different radius of holes(r=0.01 to 0.09 m for D=0.2 m ) • To study the effect of increase in hole dia. 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 r/D.

32. 32. Results and Discussions • The max. stresses generated due to various r/D, on the flat plate configuration are plotted and studied • The max. stress generated is almost constant for lower r/D, however for r/D>0.25 it increased exponentially • The stress distribution across the width of the plate is plotted • The stress distribution across the width of the plate is non linear for lower r/D, however for larger r/D it is a linear curve • The stress distribution around the hole is studied.
