Essential work of fracture and absorbed energy by Charpy impact test of TRIP780 1.5 mm thick sheet steel Kerbschlagarbeit und absorbierte Energie bei der Charpy‐Schlagprüfung an 1,5 mm dickem Restaustenitstahlblech (HCT 780)

Materialwissenschaft und Werkstofftechnik, Volume 57, Issue 9, Page 895-907, September 2026.
The study demonstrated that absorbed energy (Charpy impact test) and fracture toughness (EWF test) are essential for evaluating the mechanical performance of thin sheet metallic materials. Transformation‐induced plasticity (TRIP) steels have been extensively studied concerning their mechanical performance under monotonic loading and conventional ...

Geometry‐Encoded Programmable Mechanics in Single‐Material Dual‐Phase Metamaterials

Small, Volume 22, Issue 50, 7 September 2026.
Inspired by the unique soft‐hard heterogeneous architecture of nacre, this study proposes a novel class of dual‐phase (DP) metamaterials. The DP metamaterials exhibit programmable nonlinear mechanical responses, tailored failure processes, and enhanced energy absorption by systematically varying the spatial coding patterns of soft‐hard unit cells ...

Effect of Foam Faces and Butterfly Auxetic Core on Sandwich Nanoplate Vibration and Buckling

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 106, Issue 8, August 2026.
ABSTRACT This research examines the thermomechanical vibration and buckling properties of a three‐layer sandwich nanoplate, which consists of foam face layers and a butterfly‐shaped auxetic core. The formulation is developed based on Hamilton's principle and higher‐order shear deformation theory (HSDT), utilizing an analytical Navier‐type solution to ...

Low Cycle Repetitive Loading of Ti‐6Al‐4V‐Epoxy Composite Lattice Structures for Enhanced Energy Dissipation and Damage Tolerance

Advanced Engineering Materials, Volume 28, Issue 14, 22 July 2026.
Composite Ti–6Al–4V–epoxy lattice structures are additively manufactured and epoxy infiltrated for cyclic loading. At low lattice volume fractions, hybridization produces synergistic gains in stiffness and energy dissipation. At higher volume fractions, synergy diminishes, although composites still exceed metallic lattices in specific energy ...
