SS-V: 1170 Stress Concentration of a Plate with Eccentric Hole

Test No. VS18 Find the stress concentration in a plate with eccentric hole.

Definition



Figure 1.
Plate is fixed at one end and pressure of 1 psi is applied on the other end of the plate. The units are IPS.
Model Dimensions
a = 1 in
c = 4 in
e = 16 in
