The Identification of Selected Imperfections of Electric Traction Motors [PDF]

, 2013
Electric traction motors of rail vehicles operate in very harsh conditions. This is due to their varying load and power fluctuations, as well as their exposure to high humidity, excessive shocks, dust and changing ambient temperature.These conditions can

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
