Journal ArticleDOI
Modelling the electro-mechanical properties of PPy/epoxy conductive composites
TL;DR: In this article, the electrical and mechanical properties of polypyrrole (PPy) and epoxy were determined by applying appropriate periodic boundary conditions (PBCs) to the representative volume elements of the material nano-structure.
Journal ArticleDOI
Determination of mode I dynamic fracture toughness of IM7-8552 composites by digital image correlation and machine learning
Rafael de Azevedo Cidade,Daniel Scandiuzzi Valença de Castro,E. M. Castrodeza,Peter Kuhn,Giuseppe Catalanotti,José Xavier,Pedro P. Camanho +6 more
TL;DR: In this article, an optical experimental procedure for evaluating the J-integral from full-field displacement fields under dynamic loading is proposed, which is applied to measure the Jintegral in the dynamic compressive loading of fiber-reinforced composites and to calculate the dynamic fracture toughness associated with the propagation of a kink-band.
Journal ArticleDOI
Measuring the intralaminar crack resistance curve of fibre reinforced composites at extreme temperatures
R.F. Pinto,R.F. Pinto,Giuseppe Catalanotti,Giuseppe Catalanotti,Pedro P. Camanho,Pedro P. Camanho +5 more
TL;DR: In this paper, the size effect law of scaled double-edge-notched (DEN) specimens is used to obtain the crack resistance curves associated with longitudinal failure of polymer composites.
Book ChapterDOI
Three-dimensional invariant-based failure criteria for transversely isotropic fibre-reinforced composites
TL;DR: In this paper, failure criteria for polymer composites reinforced by unidirectional fibres are proposed based on an invariant quadratic formulation based on structural tensors that accounts for the preferred directions of the transversely isotropic material.
Journal ArticleDOI
High strain rate characterisation of intralaminar fracture toughness of GFRPs for longitudinal tension and compression failure
TL;DR: In this article, the elastic parameters, strength, and intralaminar fracture toughness for an E-glass polymer composite material system, statically and at high strain rate, adapted methodologies previously developed by the authors for different carbon composites.
