Question

In FEM, what does the simple two-dimensional plate theories account for?

(a) The kinematics of bending deformation of thin bodies without to transverse loads

(b) The kinematics of bending deformation of thin bodies subjected to transverse loads

(c) Thin bodies subjected to transverse loads without bending deformation

(d) Thin plates subjected to transverse loads with bending deformation

I had been asked this question during a job interview.

I'm obligated to ask this question of Classical Plate Model topic in division Bending of Elastic Plates of Finite Element Method

Answer 1

The correct option is (b) The kinematics of bending deformation of thin bodies subjected to transverse loads

The explanation is: The term “plate” refers to solid bodies that are bounded by two parallel planes whose lateral dimensions are large compared with the separation between them (i.e., the thickness of the plate). In most cases, the thickness is no greater than one-tenth of the smallest in-plane dimension. Geometrically, plate problems are similar to the plane stress problems except that plates are also subjected to transverse loads. Thus, the simple two-dimensional plate theories account for the kinematics of bending deformation of thin bodies subjected to transverse loads.
