Pressure Loaded Beam (Small Strains)
A cantilever of length , depth and width , loaded by a uniform pressure load from above. The cantilever is supposed to be fixed at and . The depicted boundary conditions do not restrict transverse deformation which occurs due to the nonzero Poisson’s number. The maximum deflection of the structure is tested.
Two cantilever materials are used:
where is the bulk modulus and is the shear modulus.
The maximum deflection is given by , where the Poisson's number is given by .
In ANSYS the problem is solved using quadratic elements (SOLID186). In femCalc the same number of BRICK60 elements with linear pressure interpolation was used.
