Special Issue Information

Dear Colleagues,

In recent years, there has been an increase in the utilisation of advanced composites as primary structural materials due to their outstanding properties. The structural and mechanical properties, such as elongation, fatigue strength, fracture toughness, plasticity, etc., are subjected to extensive research and discussion. Experimental investigations, alongside mathematical and computational modelling, aim to enhance the properties of composite varieties as significant structural materials, to address existing and rising challenges in different industrial sectors. The main target of this Special Issue is to publish original research articles, critical reviews, as well as practical studies. The primary objective is to investigate the deformation and mechanics of fracture for composite materials used in various industrial applications, including energy, aerospace, marine engineering, etc., to increase fatigue strength and structural lifespan.

This Special Issue is intended to contribute to discussions and future developments on this essential theme, considering the applied aspects of the subject. Research areas may include, but are not limited to, the following:

  • Structural and mechanical behaviour analysis;
  • Numerical analysis and modelling of materials characteristics;
  • Deformation and fracture mechanics analysis of composite materials;
  • Novel methods for assessing the mechanical properties evolution in advanced composite materials;
  • Advanced manufacturing technologies to fabricate composite materials;
  • Developing multifunctional materials and structures;
  • Various industrial applications of composite materials.

We are pleased to invite you to submit a manuscript for this Special Issue and we look forward to your contributions.

Microscopic fabric changes are the main reason for the complex physical and material properties of Yellow River ice at the macroscale. To study the physical and material properties of Yellow River ice, Yellow River ice was taken as the research object, and definition and determination methods for the representative volume element (RVE) of the Yellow River ice based on its computed strength at the microscale were proposed. A micromechanical numerical model for Yellow River ice was built, the corresponding macromechanical properties were simulated, and the RVE size of the macromechanical strength of the Yellow River ice was determined to be 250 mm. The uniaxial compressive strength of river ice in different working conditions was simulated and analyzed, and the accuracy and effectiveness of the RVE of the calculated strength of river ice were verified. The research results provide a reference for analyzing the damage process of Yellow River ice at the microscopic level, providing a theoretical basis for studying the mechanism of Yellow River ice.

Friction stir processing (FSP) offers a unique opportunity to tailor the microstructure and improve the mechanical properties due to the combination of extensive strains, high temperatures, and high-strain rates inherent to the process. Reactive friction stir processing was carried out in order to produce in situ Al/(Al13Fe4 + Al2O3) hybrid nanocomposites on wrought/as-annealed (673 K) AA1050 substrate. The active mixture of pre-ball milled Fe2O3 + Al powder was introduced into the stir zone by pre-placing it on the substrate. Microstructural characterisation showed that the Al13Fe4 and Al2O3 formed as the reaction products in a matrix of the dynamically restored aluminium matrix. The aluminium matrix means grain size was found to decrease markedly to 3.4 and 2 μm from ~55 μm and 40–50 μm after FSP using wrought and as-annealed substrates employing electron backscattered diffraction detectors, respectively. In addition, tensile testing results were indicative that the fabricated surface nanocomposite on the as-annealed substrate offered a greater ultimate tensile strength (~160 MPa) and hardness (73 HV) than those (146 MPa, and 60 HV) of the nanocomposite formed on the wrought substrate.
