Numerical simulation of low pressure die-casting aluminum wheel [PDF]
China Foundry, 2009 The FDM numerical simulation software, ViewCast system, was employed to simulate the low pressure die casting (LPDC) of an aluminum wheel. By analyzing the mold-fi lling and solidifi cation stage of the LPDC process, the distribution of liquid fraction ...

2D Skeletal Muscle Thin Film Actuators Enhance Efficiency of Biohybrid Robots
Advanced Functional Materials, EarlyView.2D skeletal muscle thin film actuators generate millinewton‐scale forces and millimeter‐scale strokes while remaining functional for over 30 days. Their force density is 20‐fold higher than 3D skeletal muscle actuators, enabling multi‐fin robots with tunable speed and multidirectional steering.
