Special Issue Information

Dear Colleagues,

The continuous evolution of advanced materials—ranging from high-performance alloys and composites to bio-inspired and additive-manufactured materials—has revolutionized industries such as aerospace, automotive, energy, and biomedical engineering. As these materials push the boundaries of performance under extreme conditions, understanding their mechanical behavior and ensuring their structural reliability has become paramount for safe and sustainable applications.

This Special Issue addresses the critical challenges in characterizing, modeling, and predicting the mechanical properties and long-term reliability of advanced materials. Key obstacles include the interplay between microstructural complexity and macroscopic performance, time-dependent degradation mechanisms (e.g., fatigue, creep, and corrosion), and the influence of multi-physical interactions (thermo-mechanical, hygro-thermal, etc.) in harsh environments. Furthermore, bridging the gap between laboratory-scale testing and real-world operational conditions remains a persistent challenge for researchers and engineers.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Materials is an international peer-reviewed open access semimonthly journal published by MDPI.

This study investigates the underwater explosion resistance of aluminum alloy octet-truss lattice sandwich structures using shock tube experiments and LS-DYNA simulations. A systematic analysis reveals key mechanisms influencing protective performance. The sandwich configuration mitigates back plate displacement through quadrilateral inward deformation, exhibiting phased deformation responses between face plates and back plates mediated by lattice interactions. Increasing the lattice relative density from 0.1 to 0.3 reduces maximum back plate displacement by 22.2%. While increasing the target plate thickness to 1.5 mm reduces displacement by 47.6%, it also decreases energy absorption efficiency by 20% due to limited plastic deformation. Fluid–structure interaction simulations correlate well with 3D-DIC deformation measurements. The experimental results demonstrate the exceptional impact energy absorption capacity of the octet-truss lattice and highlight the importance of stiffness-matching strategies for enhanced energy dissipation. These findings provide valuable insights for optimizing the design of underwater protection structures. Full article
