EnglishIn this paper, the Generalised Probabilistic Approach (GPA) recently proposed by some of the presentauthors 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 carriedout on a commercial Fibreglass composite. Then, the Primary Cumulative Distribution Function ofFailure (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 loadingconditions separately (GPA single application); (b) by collecting both the specimens subjected to tensionand 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 latterobtained from both single and joint application of GPA, is provided for each loading condition.
