Special Issue Information

Dear Colleagues,

Material failure that would lead to structural integrity reduction and affect usage life still remains one of the major concerns in various engineering fields. Failure patterns arising in solids and structures may involve brittle cracking, fatigue damage, fragmentation, and progressive interfacial cracks, etc. Usually, two or more failure patterns appear during material degradation, and the interaction between them makes the problems more complicated. In recent decades, much interest has been devoted to failure analysis by means of numerical modeling. In this regard, many numerical algorithms have been proposed and used to contribute to the modeling of failure behavior and the understanding of failure mechanisms. This Special Issue aims to collect contributions addressing recent advances in numerical algorithms and applications related to material failure modeling of solids and structures.

Potential topics include, but are not limited to, the following:

  • Novel concepts of numerical algorithms for failure modeling;
  • Discrete crack approaches, e.g., Eigenerosion method, cohesive zone models, extended finite element methods, and discontinuous Galerkin-based models;
  • Regularized crack approaches, e.g., phase field models, non-local models, and gradient-enhanced models;
  • Mesh-free-based algorithms, e.g., discrete element methods, material point methods, and reproducing kernel particle methods;
  • Coupling methods and related adaptive algorithms, e.g., (adaptive) combined discrete/finite element methods, and (adaptive) coupling material point and finite element methods;
  • Novel applications of the existing numerical methods;
  • Revealing failure mechanisms using existing numerical methods

Numerical simulations of the fracture process are challenging, and the discrete element (DE) method is an effective means to model fracture problems. The DE model comprises the DE connective model and DE contact model, where the former is used for the representation of isotropic solids before cracks initiate, while the latter is employed to represent particulate materials after cracks propagate. In this paper, a DE particle-based cohesive crack model is developed to model the mixed-mode fracture process of brittle materials, aiming to simulate the material transition from a solid phase to a particulate phase. Because of the particle characteristics of the DE connective model, the cohesive crack model is constructed at inter-particle bonds in the connective stage of the model at a microscale. A potential formulation is adopted by the cohesive zone method, and a linear softening relation is employed by the traction–separation law upon fracture initiation. This particle-based cohesive crack model bridges the microscopic gap between the connective model and the contact model and, thus, is suitable to describe the material separation process from solids to particulates. The proposed model is validated by a number of standard fracture tests, and numerical results are found to be in good agreement with the analytical solutions. A notched concrete beam subjected to an impact loading is modeled, and the impact force obtained from the numerical modeling agrees better with the experimental result than that obtained from the finite element method.

In the practical design of thin-walled composite columns, component dimensions should be wisely designed to meet the buckling resistance and economic requirements. This paper provides a novel and useful investigation based on a numerical study of the effects of the section dimensions, thickness ratio, and slenderness ratio on the critical buckling load of a thin-walled composite strut under uniaxial compression. The strut was a channel-section-shaped strut and was made of glass fiber-reinforced polymer (GFRP) composite material by stacking symmetrical quasi-isotropic layups using the autoclave technique. For the purpose of this study, a numerical finite element model was developed for the investigation by using ABAQUS software. The linear and post-buckling behavior analysis was performed to verify the results of the numerical model with the obtained buckling load from the experiment. Then, the effects of the cross-section dimensions, thickness ratio, and slenderness ratio on the critical buckling load of the composite strut, which is determined using an eigenvalue buckling analysis, were investigated. The implementation results revealed an insightful interaction between cross-section dimensions and thickness ratio and the buckling load. Based on this result, a cost-effective design was recommended as a useful result of this study. Moreover, a demarcation point between global and local buckling of the composite strut was also determined. Especially, a new design curve for the channel-section GFRP strut, which is governed by the proposed constitutive equations, was introduced to estimate the critical buckling load based on the input component dimension.
