Impact Response of Ti6Al4V Lattice Structures An Additive Manufacturing Study

Impact Response of Ti-6Al-4V Lattice Structures uniquely integrates design, manufacturing, high-temperature testing, and modeling of Ti-6Al-4V lattice structures into a comprehensive framework, addressing critical industry demands from aerospace and defense for lightweight, impact-resistant materials. By exploring the intricate interplay of lattice topology, unit cell size, strain rate, temperature, and microstructural evolution, the work offers a detailed guide for researchers and engineers seeking to push the boundaries of advanced material design. It systematically examines Ti-6Al-4V lattice structures fabricated using laser powder bed fusion (LPBF), covering the fundamentals of LPBF processing, design principles of triply periodic minimal surface (TPMS) architectures, and their deformation behavior under dynamic compression. Readers will gain valuable insights into experimental methodologies, including Split Hopkinson Pressure Bar (SHPB) testing, and learn how strain rate and temperature influence lattice performance. Additionally, the analysis covers microstructural evolution, adiabatic shear band formation, and constitutive modeling, comparing six predictive models to evaluate their accuracy and applicability. These features make the content an invaluable resource for understanding and optimizing titanium lattice structures for real-world applications.
