Design and Optimization of Floor Layers in Carbon Fiber Composites for Body‐in‐White Materials
The PSO‐BFO‐optimized partitioned carbon fiber mid‐floor achieves a 46.7% weight reduction and significantly improves the bending and torsional stiffness and modal performance of the body‐in‐white. ABSTRACT To improve the performance of the body‐in‐white (BIW) and achieve automotive lightweighting, a balanced approach across materials, techniques, and ...

Ultrahigh Stiffness and Energy Absorption Properties of Isotropic Metallic Closed Cell Microlattices
True closed cell microlattices without holes are fabricated for the first time using a novel Laser Sheet Fusion additive manufacturing technique. These microlattices exhibited isotropy in stiffness and surprisingly, strength and plasticity as well, despite orientation‐dependent failure mechanisms. Furthermore, material work hardening is shown to be key

This study introduces functionally graded auxetic TPMS metamaterials designed to stabilise negative Poisson’s ratio behaviour at large strains. By suppressing out‐of‐plane buckling and promoting sequential crushing, these graded architectures maintain predictable deformation paths and enhanced stability compared with uniform designs.

Crashworthiness Simulations with DYNA3D [PDF]
Current progress in parallel algorithm research and applications in vehicle crash simulation is described for the explicit, finite-element algorithms in DYNA3D. Two challenging algorithm research problems are addressed: problem partitioning methods and parallel algorithms for contact at material interfaces.

The work demonstrates that strategic wall‐thickness grading in diamond triply periodic minimal surface lattices enables precise tuning of deformation and failure behavior under compression. Different gradation patterns guide how and where the structure collapses, improving energy absorption or promoting controlled brittle failure.

Rib‐Reinforced Ultralight and Ultra‐Strong Shell Lattices
This study thoroughly reveals the relation between the curvature and stress direction of triply periodic minimal surface (TPMS) thin shell lattices and proposes a novel rib reinforcement design strategy to incorporate ribs along the line of asymptotes (LOA) and the line of principal curvatures (LOC) to enhance the strength of ultralight TPMS shell ...
