1. A National Institute for Materials Science (NIMS) research team has identified the mechanism by which microscopic fatigue cracks grow in metals, solving a half-century-old mystery. The team found ...

Fatigue crack growth and closure mechanisms are fundamental to understanding the durability of engineering structures subjected to cyclic loading. Over decades of research, scientists have ...

Recently, a research team led by Prof. NI Yong and Prof. HE Linghui from the University of Science and Technology of China (USTC) uncovered the propagation and toughening mechanism of tortuous crack ...

Stress-induced cracks often lead to catastrophic failure of materials. For membranes, stress loads concomitant with thermal and mechanical risks during separation will gradually produce cracks, which ...

Metal alloys crack and fail through a mechanism called "fatigue" when repeatedly loaded and strained. While it is well known how to design alloys to withstand static loads and pressures, it is very ...
