Plate Poisson's Ratio

Shokoufeh Zargar — Thu, 18 Nov 2021 02:54:49 GMT

Hello,

I have modeled a simply supported beam in Plaxis-2D and 3D, and by using a Poisson's ratio of zero the deflections are similar to theoretical values (and checked it vs. Abaqus). However, by considering a Poisson's ratio of 0.3 the displacements are reduced which is not consistent with expected behavior (by increasing the Poisson's ratio we expect shear modulus to be decreased, therefore resulting in increase of shear deformations). Also, by considering P-delta effects (updated mesh) in Plaxis the displacements decrease which is opposite of the expected behavior.
