Özet
Lightweight
structural systems with high strength and enhanced energy absorption capacity
are of critical importance in the aerospace industry due to their direct impact
on fuel efficiency, operational costs, and environmental sustainability.
Lattice structures have emerged as an effective solution to meet these
requirements by offering high load-bearing capability with significantly
reduced material usage. In this study, a novel Sp³-inspired lattice structural
element, derived from atomic orbital hybridisation principles, is proposed and
investigated. Sp³ lattice
structures are three-dimensional cellular architectures, in which S
denotes space-filling and P denotes periodic topology,
characterised by interconnected strut networks exhibiting high
stiffness-to-weight efficiency.The structure is designed as a braided prismatic
metal beam and compared with a conventional solid structural configuration
under equivalent geometric conditions.
A comprehensive
static Finite Element Method (FEM) analysis was conducted to evaluate the
structural performance of both configurations under mid-span loading,
end-region compressive loading, and end-region bending loading. Galvanised iron
material properties were adopted, and stress, displacement, and strain
responses were analysed. The numerical results demonstrate that the Sp³ lattice
structure exhibits substantially lower stress and strain levels under mid-span
and compressive loading conditions, indicating superior stiffness and load
distribution characteristics. Although higher stress levels were observed under
end-region bending, the Sp³ lattice maintained comparable displacement
behaviour while offering significant manufacturing efficiency advantages.
The findings
confirm that Sp³-inspired lattice structures provide a promising design
approach for aerospace structural applications requiring lightweight,
high-strength, and energy-absorbing components. This study also highlights the
potential of multidisciplinary design strategies, where atomic-scale principles
are effectively translated into macro-scale structural systems.
