Special Issue Information

Dear Colleagues,

Due to improved load-bearing capacity, the provision of optimized structural solutions and the effective creation of synergies between structural materials, thin-walled structures, and composite structures have recently attracted widespread attention from researchers in many areas ranging from aerospace, automotive, bridges, ships, wind power, industrial buildings, and sports. The science and technology of thin-walled structures and composite structures have undergone intense development over the last several decades; nevertheless, these topics are still in a phase of progression.

This Special Issue on “Advances in Thin-walled Structures and Composite Structures” primarily aims to collect ideas, analyses, proposals, and opinions from several scholars from different areas that could outline possible future achievements and challenging improvements in this field. Original contributions on the design, research and development studies, experimental investigations, theoretical analysis, computational methods, and fabrication techniques relevant to the application of thin-walled structures and composite structures are welcome. Topics of interest include (but are not limited to):

  • Experiments of advanced thin-walled structures and composite structures;
  • Mechanical analysis of advanced thin-walled structures and composite structures;
  • Numerical simulations of advanced thin-walled structures and composite structures;
  • Damage and failure of advanced thin-walled structures and composite structures;
  • Design and application of advanced thin-walled structures and composite structures;
  • Multiscale modeling of advanced composite materials and structures.

This paper presents an innovative method of constructing energy absorbers, whose primary function is to effectively transform kinetic energy into strain energy in events with high deformation rates. Hybrid specimens are proposed considering thin-walled windowed metallic tubes filled with 3D-printed hexagonal honeycombs made of PET-G and ABS thermoplastic. The patterned windows dimensions vary from 20 × 20, 20 × 30, 15 × 20 and 15 × 30 mm2. Although using polymers in engineering and thin-walled sections is not new, their combination has not been explored in this type of structure designed to withstand impacts. Specimens resist out-of-plane quasi-static axial loading, and test results are analyzed, demonstrating that polymer core gives the samples better performance parameters than unfilled samples regarding energy absorption (Ea), load rate (LR), and structural effectiveness (η). An optimization procedure using specialized software was applied to evaluate experimental results, which led to identifying the optimal window geometry (16.4 × 20 mm2, in case) and polymer to be used (ABS). The optimized sample was constructed and tested for axial compression to validate the optimization outcomes. The results reveal that the optimal sample performed similarly to the estimated parameters, making this geometry the best choice under the test conditions. Full article
