What is it about?
The present paper deals with the computational study of unidirectional glass fibre reinforced epoxy composites in short-beam bending test and the comparison of the induced results with experimental and analytical results.

Why is it important?
The main aim of this work is to evaluate the performances of composite beams under three-point bending and to study the interlaminar shear failure by investigating the unidirectional fiber reinforced epoxy composites experimentally and numerically via the Finite Element Analysis (FEA). Moreover, it is possible to obtain the stress distribution at the supports and at the loading points where usually there is an abrupt variation due to the indentation existing because of the noses.
Perspectives
The aim of the results presented in this study was to investigate in which level the compu-tational analysis approaches the classical beam theory as well as the experimental results and how the orientation of the fiber influences the maximum values of normal and shear stresses . Another important task also was to determine the differences between theoret-ical/experimental values with computational ones when approaching the loading points and the supports where some assumptions may be not valid or are doubtful.
