The introduction of the spread-tow thin-ply technology enabled the development of
composite plies as thin as 0.020 mm. The availability of composite plies with a broader …

This work represents the first step towards the application of machine learning techniques in
the prediction of statistical design allowables of composite laminates. Building on data …

The design and certification process of composite structures relies on the building-block
approach, which starts from the mechanical characterization of the material at coupon-level …

For the past six years, we have been benefiting from the discovery by Tsai and Melo (2014)
that the trace of the plane stress stiffness matrix (tr (Q)) of an orthotropic composite is a …

This paper provides an overview of the current approaches to predict damage and failure of
composite laminates at the micro-(constituent), meso-(ply), and macro-(structural) levels …

The development of numerical tools to complement the experimental determination of
structural design parameters is of key importance to hasten the certification process of new …

Thin prepregs with thickness of less than 0.06 mm support flexible lamination design
because it is possible to apply various stacking sequences. The objective of this study is to …

Brittle fracture tests are carried out on Brazilian disk specimens containing a circular hole.
The experimental campaign involves two different polymeric materials, Polymethyl …

The brittle crack initiation from a circular hole in an infinite slab subjected to remote biaxial
loading is investigated by means of the coupled finite fracture mechanics criterion, focussing …

In this paper, the coupled Finite Fracture Mechanics criterion is extended to assess the finite
fatigue life of orthotropic notched laminated composites. The approach is validated through …
