Special Issue Information

Dear Colleagues,

Polymer composites have attracted great research interest in many areas and industries, such as aerospace engineering, transportation industry, marine engineering, construction industry, sports facilities, medical industry, etc., due to their advanced properties. As a result, it is of great significance, as well as very challenging, to investigate their mechanical properties like strength, modulus, toughness, energy absorption capacity, failure mechanism, etc., and the structural properties of polymer composites at different loading conditions to guarantee and optimize the safety and reliability of the structures during different applications. The relevant areas include, but are not limited to, the following topics:

  • Fiber-reinforced polymer composites with multi-functions;
  • Structural properties of advanced polymer composites;
  • Mechanical properties of polymer metamaterials with advanced structures;
  • Dynamic behavior and failure of composites including plasticity and fracture;
  • Design and optimization of soft composites;
  • Additive manufacturing composites and structures.

Abstract
The current study focuses on the production and experimental examination of sandwich beams consisting of an aluminum face sheet and 3D-printed honeycomb cores that are filled with magnetorheological elastomer (MRE). These cores are loaded with different ratios of (75/25)% and (50/50)% elastomer and [...] Read more.
The current study focuses on the production and experimental examination of sandwich beams consisting of an aluminum face sheet and 3D-printed honeycomb cores that are filled with magnetorheological elastomer (MRE). These cores are loaded with different ratios of (75/25)% and (50/50)% elastomer and magnetic particles, measured by weight. In order to ascertain the dynamic characteristics of sandwich beams, the constructed specimens were subjected to classic shock (free vibration) experiments, and these experiments were conducted under two conditions: with and without the application of a changing magnetic field at the free end and center of the beam. The results of the experiments suggest that the attenuation of the damping ratio exhibited satisfactory performance, particularly with respect to the structures that were being examined. The sandwich beam constructions proposed exhibited the ability to alter the damping ratio, damping coefficient, and stiffness through the application of a magnetic field. Nevertheless, an escalation in the applied magnetic field resulted in a reduction in stiffness values, while the values of the damping ratio and damping coefficient increased. Furthermore, significant variations in damping were observed when the magnets were located in the central regions of the structures. Full article
