L = 250 in
D = 2 in
t = 0.1 in Loading
g = 386 in/sec2 Analysis Assumptions and Modeling Notes
The loading g, which is constant in magnitude and direction around the circumference of the pipe, is applied as
the sum of two harmonically varying loads. Each load has one wave around the circumference and is 90° out of
phase with the other.
