“…In this study, the transport problem was not explicitly resolved and, instead, a uniform moisture distribution was assumed. Ye and Zhang [48] formulated a coupled phase field model that accounted for the interaction of stresses, moisture and crack propagation in composite materials. Their framework incorporated the hygroscopic expansion phenomenon due to moisture diffusion and the viscoelastic behaviour of polymer matrix.…”

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.

“…We have also developed phase-field models for composite interface damage 30,31 and multi-field coupled fracture. 32,33 Although serving well for the variational description of cracks, the phase-field method often faces computational bottlenecks when modeling and solving complex heterogeneous structures with finite elements, as with all methods that rely on finite-element solution techniques.…”

The intractable multiscale constitutives and the high computational cost in direct numerical simulations are the bottlenecks in fracture analysis of heterogeneous materials. In an attempt to achieve a balance between accuracy and efficiency, we propose a mathematically rigorous phase‐field model for multiscale fracture. Leveraging the phase‐field theory, the difficulty of discrete‐continuous coupling in conventional cross‐scale crack propagation analysis is resolved by constructing a continuum description of the crack. Based on the asymptotic expansion, an equivalent two‐field coupled boundary‐value problem is well‐defined, from which we rigorously derive the macroscopic equivalent parameters, including the equivalent elasticity tensor and the equivalent fracture toughness tensor. In our approach, both the displacement field and the phase‐field are simultaneously expanded, allowing us to obtain a fracture toughness tensor with diagonal elements of the corresponding matrix controlling anisotropic fracture behavior and non‐diagonal elements governing crack deflection. This enables multiscale finite element homogenization procedure to accurately reproduce microstructural information, and capture the crack deflection angle in anisotropic materials without any a priori knowledge. From the numerical results, the proposed multiscale phase‐field method demonstrates a significant reduction in computation time with respect to full‐field simulations. Moreover, the method accurately reproduces physical consistent anisotropic fracture of non‐centrosymmetric porous media, and the experimentally consistent damage response of fiber‐reinforced composites. This work fuses well‐established mathematical homogenization theory with the cutting‐edge fracture phase‐field method, sparking a fresh perspective for the fracture of heterogeneous media.

“…Moreover, the moisture and humidity of the environment influence the mechanical parameters of viscoelastic composites. Under a complex external load, the mechanisms of moisture intrusion, water penetration, and diffusion in viscoelastic composites has attracted a lot of investigation [ 34 , 35 ]. Ye and Zhang [ 35 ] established a thermodynamically consistent moisture diffusion model for coupling the moisture diffusion effect and viscoelastic response of the multiphase viscoelastic composites, developed a two-constituent phase-field fracture model for describing the hygroscopic swelling behaviors at the multiphase interfacial decohesion of viscoelastic polymer material, and proposed a crack filter theory for characterizing the moisture flux propagation at the interface between the multiphases.…”

This analysis investigated the impact wave response and propagation on a composite sandwich shell when subjected to a low-velocity external shock, considering hygrothermal effects. The sandwich shell was crafted using face layers composed of functional gradient metal–ceramic matrix material and a core layer reinforced with negative Poisson’s honeycomb. The honeycomb layer consisted of a combination of viscoelastic polymer material and elastic material. The equivalent parameters for the functional gradient material in the face layers were determined using the Mori–Tanaka and Voigt models, and the parameters for the negative Poisson’s ratio honeycomb reinforcement core layer were obtained through Gibson’s unit cell model. Parameters relevant to a low-velocity impact were derived using a modified Hertz contact law. The internal deformations, strains, and stress of the composite sandwich shell were described based on the higher-order shear deformation theory. The dynamic equilibrium equations were established using Hamilton’s principle, and the Galerkin method along with the Newmark direct integration scheme was employed to calculate the shell’s response to impact. The validity of the analysis was confirmed through a comparison with published literature. This investigation showed that a multilayer negative Poisson’s ratio viscoelastic polymer material honeycomb-cored structure can dissipate impact wave energy swiftly and suppress shock effectively.
