Researchers have developed a mathematical framework to design knee-like joints in robots, called rolling ...

Consider the marvelous physics of the human knee. The largest hinge joint in the body, it has two rounded bones held together by ligaments that not only swing like a door, but also roll and glide over ...

Design engineers routinely rely on bolted joints, yet most guidance focuses on axial stiffness—often overlooking moment (pitch) stiffness, which can dominate compliance in ...

A partnership between the Air Force Research Laboratory and industry could help usher in a new era of advanced aircraft assembly. Testing performed by AFRL showed promising results for the use of ...

The scatter of bolt clamping force tightened by the conventional torque control method very often causes loosening and fatigue failure of bolted joints. Different values of frictional coefficients ...
