Flat Plate Bending Calculator

Calculate deflection and bending stress for circular and rectangular plates under uniform pressure with various edge conditions.

For circular: radius. For rectangular: shorter side length.
mm
Thickness of the plate.
mm
Uniformly distributed pressure on the plate.
MPa
Young's modulus of plate material. Steel: 207 GPa.
GPa
Poisson's ratio. Steel: 0.3, Aluminum: 0.33.
