“…The phase field fracture model builds upon Griffith's thermodynamics principles [20] and has been widely used to predict the evolution of cracks in a wide range of materials, including rock-like materials [21,22], ceramics [23,24], ductile metals [25,26], functionally graded materials [27,28], porous media [29,30], shape memory materials [31,32], ice [33,34] and composites [36,36]. In addition, it has been successfully employed to model fracture and bridging behaviour in fibre-reinforced composite materials at the micro-scale level [37,38].…”

This paper investigates the effect of moisture content upon the degradation behaviour of composite materials. A coupled phase field framework considering moisture diffusion, hygroscopic expansion, and fracture behaviour is developed. This multi-physics framework is used to explore the damage evolution of composite materials, spanning the micro-, meso- and macro-scales. The micro-scale unit-cell model shows how the mismatch between the hygroscopic expansion of fibre and matrix leads to interface debonding. From the meso-scale ply-level model, we learn that the distribution of fibres has a minor influence on the material properties, while increasing moisture content facilitates interface debonding. The macro-scale laminate-level model shows that moisture induces a higher degree of damage on the longitudinal ply relative to the transverse ply. This work opens a new avenue to understand and predict environmentally assisted degradation in composite materials.
