In this project, we are learning about stress concentration on plates with non-circular holes.
Two hole geometries are being analyzed. Ellipse with a/b= 2 and slot geometry with h/c=20 and circular ends with r=1mm and r= 3mm. Please look at the accompanying paper uploaded in blackboard. Material of the pate is elastic carbon steel.
Part 1:
Starting with hole and slot orientations at 90 degrees:
Case 1: Apply uniaxial load of 300 kN Case 2: Apply equal bi-axial loads 300kN
Case 3: Apply bi-axial loads 300kN and -300kN calculate stress concentration factor for all cases Analysis:
Tabulate all results neatly and organized.
Plot case 1 against theoretical value for plate with circular hole from plot A-15-1 above. Plot cases 2 and 3 to show effect of addition of biaxial loads and variation of load direction
Part 2:
Starting with hole and slot orientations at 45 degrees:
Case 1: Apply uniaxial load of 300 kN Case 2: Apply equal bi-axial loads 300kN
Case 3: Apply bi-axial loads 300kN and -300kN calculate stress concentration factor for all cases Analysis:
Tabulate all results neatly and organized.
Plot case 1, part 1 and part 2
Plot cases 2 and 3, for part 1 and part 2
