This calculator computes the displacement of a simply-supported circular plate under a uniformly distributed load.

Inputs
Loading:   Uniform load p =  
 Geometry: 
 Radius ro =    
 Thickness h =    
 Material
 Young's modulus E =    
 Poisson's ratio nu =  
Output: 
 Unit of displacement w =  
 Unit of stress =  

 
 
Displacement

Notice that the deformation is axial symmetric and it is only a function of the radius.

Hence, = 0.271728515625 mm ~ 0.272 mm

Stress
Mr
Mt

The maximum bending moment occurs at the center of the plate, r = 0.

Mmax

The maximum stress occurs at the center of the plate near surface, r = 0, z = ±h/2.

max = 0.7734375 MPa ~ 0.773 MPa
