Coupled visco-mechanical and diffusion void growth modelling during composite curing [PDF]

open access: yes, 2010
Most critical processing step during long fiber reinforced epoxy matrix composite laminate manufacturing is the polymerization stage. If not optimized, it gives birth to defects in the bulk material, such as voids.

Computational design for 4D printing of topology optimized multi-material active composites

open access: yesnpj Computational Materials, 2023
Recent efforts on design for four-dimensional (4D) printing have considered the spatial arrangement of smart materials and energy stimuli. The development of multifunctional structures and their desired mechanical/actuation performances require tackling ...

Measuring the notched compressive strength of composite laminates: Specimen size effects [PDF]

open access: yes, 2008
Large fibre reinforced composite structures can give much lower strengths than small test specimens, so a proper understanding of scaling is vital for their safe and efficient use.

Effect of intra-ply voids on the homogenized behavior of a ply in multidirectional laminates [PDF]

open access: yes, 2018
This work focuses on the effect of intra-ply voids on the homogenized nonlinear behavior of a ply in multidirectional composites. Voids were modeled explicitly on the fiber scale and linked to the ply-scale by the recently developed two-scale framework ...
