10 Abr New paper on Discrete Ply Modelling of Carbon Fiber Thermoplastics in Composite Structures
A researcher from AMADE (José Manuel Guerrero), along with colleagues from the Insitute Clément Ader (Christophe Bouvet, John-Eric Dufour, and Joel Serra), has published a new paper in Composite Structures, titled:
“Discrete ply modelling of aeronautical intermediate-scale notched carbon fibre reinforced thermoplastic specimens subjected to multiaxial loading”
This study employs the Discrete Ply Model (DPM) to replicate intermediate-scale experimental tests conducted on carbon fiber reinforced thermoplastic notched specimens. The tests were performed under tension, shear, and combined tension and shear loading, and presented early buckling and the subsequent development of post-buckling for almost all the loading. The numerical results obtained from the DPM simulations provided predictions with reasonable accuracy for the material’s strength, strain fields, deformed shapes, buckling modes, crack propagations, and failure patterns.
Finite element models developed at the mesoscale level are usually validated by comparing with typical coupon-scale specimens under uniaxial loads, which are not representative of aeronautical structures subjected to complex multiaxial loads. This paper goes one step forward by presenting a complex finite element model, using the DPM strategy, reproducing intermediate-scale specimens, more representative of real life aeronautical structures, under multiaxial loads.
This publication represents another step forward in numerical modeling for composite aerostructures, reinforcing AMADE’s expertise in advanced materials research.
