Special Issue Information

Dear Colleagues,

Multiphysics analyses of damage initiation and subsequent growth in natural solids and engineered materials such as composites, functionally graded materials, etc. are important to guide the design and ensure the sustainability of engineering structures. The current understanding of damage initiation and growth in materials, especially engineered materials, is incomplete due to the complexity of the damage processes caused by the underlying material inhomogeneity. Moreover, the technical capabilities of current numerical techniques to model such damage initiation and growth are not sufficiently robust to model the complete evolution of damage processes starting from initiation, growth, propagation that eventually leads to the failure of engineering structures. This has fueled research on novel discretization techniques such as enrichment methods, variational fracture, local and non-local damage models, cohesive zone models, and other multiscale approaches.

The guest editors of this Special Issue aim to attract contributions from practicing engineers, mathematicians, and computational mechanics, among others, on computational approaches to model fracture and damage in engineered materials, such as composites and functionally graded materials subjected to quasi-static and dynamic loading conditions, as well as both mechanical and multi-physics damage modeling. The topics of interest include but are not limited to enrichment methods, mesh-free methods, phase field models, computational homogenization and reduced order models, spatiotemporal techniques to model multiphysics processes, regularized models, and stability analyses.

The prediction of damage and failure to fiber-reinforced polymer composites in extreme environments, particularly when subjected to impact loading, is a crucial issue for the application and design of protective structures. In this paper, based on the prototype microelastic brittle (PMB) model and the LaRC05 composite materials failure model, we proposed a bond-based peridynamic (BB-PD) model with the introduction of plastic hardening of the resin matrix for fiber-reinforced polymer composites. The PD constitutive relationships of the matrix bond and interlayer bond under compressive loading are considered to include two stages of linear elasticity and plastic hardening, according to the stress–strain relationship of the resin matrix in the LaRC05 failure model. The proposed PD model is employed to simulate the damage behaviors of laminated composites subjected to impact loading. The corresponding ballistic impact tests of composite laminates were carried out to observe their damage behaviors. The PD prediction results are in good agreement with the ballistic experimental results, which can verify the correctness and accuracy of the PD model developed in this study in describing the impact damage behaviors of composite materials. In addition, the characteristics and degree of damage in composite laminates are analyzed and discussed based on this PD model. The difference in the impact resistance of composite laminates with different stacking sequences is also studied using the numerical simulation results. Full article
