ABSTRACT
This paper is devoted to a clamped sandwich beam with an individual functionally graded
core under a uniformly distributed load. A non-linear shear deformation theory is developed
with consideration of the classical shear stress formula for beams. Two differential equations
of the equilibrium of the beam are obtained based on the principle of stationary total
potential energy. The shear effect function and the relative deflection line of the beam are
determined. Moreover, a numerical FEM model (Ansys system) of this beam is elaborated.
Detailed calculations of exemplary beams are realised using two methods, analytical and
numerical FEM.
