Abstract

In this paper, the Generalised Probabilistic Approach (GPA) recently proposed by some of the present authors is applied in order to analyse the short fibre-reinforced materials behaviour at failure. Firstly, an experimental campaign consisting of tension tests, three- and four-point bending tests is carried out on a commercial Fibreglass composite. Then, the Primary Cumulative Distribution Function of Failure (PCDFF) is determined by employing both experimental and numerical results. In particular, the PCDFF is derived in two cases: (a) by considering the specimens subjected to the above three loading conditions separately (GPA single application); (b) by collecting both the specimens subjected to tension and those subjected to three-point bending in order to constitute a unique set (GPA joint application). Finally, a comparison between experimental failure probability values and PCDFF, being the latter obtained from both single and joint application of GPA, is provided for each loading condition.
