Displacement

wat loading = w(a, b) = 0.175163322221 mm ~ 0.175 mm

The above displacement is based on the first 2 2 = 4 terms of the series solution.

Stress
Mx
My

= 1.97576308103 MPa ~ 1.98 MPa

= 1.97576308103 MPa ~ 1.98 MPa

The above calculation is based on the first 2 2 = 4 terms of the series solution.
