Tough, Ductile, and Strong Hard‐Soft Cementitious Composite Enabled by Multi‐Material Additive Manufacturing

Advanced Materials, EarlyView.
Drawing inspiration from the layered hard‐soft architecture found in sea sponges, this work establishes a new framework for architected cementitious composites (ACC) through multi‐material additive manufacturing (MMAM) process. The integration of mortar and elastomer phases into layered architectures enables synergistic toughening mechanisms, including

Uncoupled Fracture Indicator Dependent on the Third Invariant and the Level of Ductility: Applications in Predominant Shear Loading

Applied Sciences
This contribution presents an improved ductile fracture indicator that is dependent on the normalized third invariant and the plastic strain at fracture, which is in turn dependent on the stress state of the material.
