Special Issue Information

Dear Colleagues,

Advanced composites, e.g., continuous/short fibre or particle-reinforced composite structures, etc., are attracting increasing attention in industrial applications due to their excellent performance, i.e., high mechanical properties in terms of stiffness- and strength-to-weight ratios, when compared to their counterparts. In recent years, significant advances have been witnessed in the mechanics and design of composite structures with respect to novel design, fabrication, and characterisation methods. As such, this Special Issue has a particular focus on, but is not limited to, the mechanics and design of advanced composites, with respect to advanced design, fabrication, and characterisation for high-performance composite materials/structures.

Some particular subjects are mentioned here for reference and submission, e.g.,

  • Continuous/short fibre/particle-reinforced composites.
  • New theoretical or numerical methods.
  • Dynamic impact and responses.
  • Damage mechanisms and tolerance.
  • Structural analysis and design optimisation.
  • Fatigue and life-cycle assessment.
  • Structural health monitoring.
  • Interface properties and strength.
  • Constitutive relations and multiscale modelling.
  • Composite sandwich structures and others.
  • Advances in the mechanics and design of advanced composites.

In this Special Issue, research-, development-, and application-related submissions on the mechanics of advanced composites and all other related domains are welcomed.

Thermoplastic composites are continuously replacing thermosetting composites in lightweight structures. However, the accomplished work on the fatigue behavior of thermoplastics is quite limited. In the present work, we propose a numerical modeling approach for simulating fatigue delamination growth and predicting the residual tensile strength of quasi-isotropic TC 1225 LM PAEK thermoplastic coupons. The approach was supported and validated by tension and fatigue (non-interrupted and interrupted) tests. Fatigue delamination growth was simulated using a mixed-mode fatigue crack growth model, which was based on the cohesive zone modeling method. Quasi-static tension analyses on pristine and fatigued coupons were performed using a progressive damage model. These analyses were implemented using a set of Hashin-type strain-based failure criteria and a damage mechanics-based material property degradation module. Utilizing the fatigue model, we accurately foretold the expansion of delamination concerning the cycle count across all interfaces. The results agree well with C-scan images taken on fatigued coupons during interruptions of fatigue tests. An unequal and unsymmetric delamination growth was predicted due to the quasi-isotropic layup. Moreover, the combined models capture the decrease in the residual tensile strength of the coupons. During the quasi-static tension analysis of the fatigued coupons, we observed that the primary driving failure mechanisms were the rapid spread of existing delamination and the consequential severe matrix cracking.
