The paper presents the results of a combined numerical and experimental study for validation of
a new three-dimensional specialized finite element, used for modelling the behaviour of laminated
composite materials, reinforced with fibers. First, the stress and strain state in a circular plate
loaded with an uniformly distributed force and fixed on the contour is evaluated using the
proposed finite element. Two types of laminated composites are considered, in order to test the
behaviour of the proposed element and the models conceived for calculus of laminated composites
having different structures. To validate the new element, calculations were made also using the
finite element code ANSYS-11. In the second part, the results of an experimental study on the
behavior of plates made of the considered laminated composites are presented and compared
with the previous numerical ones. The good agreement between the obtained data showed that
the new proposed element is adequate for modelling the bending behaviour of fiber reinforced
multilayer composite materials.
