Effect of thickness variation upon plates subjected to bending
Abstract
The variation of the plate thickness is an element that introduces a major difficulty in solving the differential equations of the deformed middle surface, because the plate rigidities are also variable.
In the paper, the effect of the thickness variation upon shear forces is presented. These shear forces must be corrected by adding the shear stresses caused by bending and twisting moments.
A physical interpretation is given to these corrections and the separation of effects is also pointed out. There are also discussed the additional energy effects caused by thickness variation.
