SS-V: 1190 Stress Concentration of a Plate with Semi-circular Holes

Test No. VS20 Find the stress concentration in a plate with semi-circular holes.

Definition



Figure 1.
The plate is fixed at one end a pressure load of 1 psi is applied on the other end. The units are IPS.
Model Dimensions
a = 1 in
H = 5 in
r = 0.5 in
h =0.1 in
H/r = 10
