eFunda: Plate Calculator -- free-clamped annular plate with ring loading

This calculator computes the displacement of an annulus plate, clamped on the inner edge, under a ring load.

Inputs

Loading:

Ring Loading P_r =
Loading Radius r_L =

Geometry:

Young's modulus E =
Poisson's ratio =

Output:

Unit of displacement w =
Unit of stress =

Displacement

w_max = w(r = r_o) = 0.207125815105 mm 0.207 mm

Stress

The maximum bending moment occurs at the fixed edge of the plate, r = r_i.

The maximum stress occurs at the fixed edge of the plate near surface, r = r_i, z = ±h/2.

_max = 2.25 MPa 2.25 MPa
