Researchers have created a polymer "Chinese lantern" that can snap into more than a dozen curved, three-dimensional shapes by compressing or twisting the original structure. This rapid shape-shifting ...

Traditional mode shape identification methods are based mostly on acceleration responses, and many hardware devices must be installed. On the basis of monophotogrammetry, the dynamic displacement ...

Automotive wheels are critical components for vehicular safety, with the rim subjected primarily to radial bending loads during operation. Balancing rim thickness and structural integrity under these ...
