Continuum Mechanics Modeling of Flexible Spring Joints in Surgical Robots

Advanced Robotics Research, EarlyView.
A new mechanical model of a tendon‐actuated helical extension spring joint in surgical robots is built using Cosserat rod theory. The model can implicitly handle the unknown contacts between adjacent coils and numerically predict spring shapes from straight to significantly bent under actuation forces.

Capillarity-induced mechanical behaviors of a polymer microtube surrounded by a droplet

AIP Advances, 2014
The capillary force of a liquid drop has a great impact on the mechanical behaviors of a polymer microtube. To further explore this capillary effect, we examine the buckling condition and finite deformation of a hollow microfiber surrounded by a droplet.

Pseudo-bulk forming of thin-walled hollow components based on the self-consistency of internal pressure and shell deformation

Materials & Design
Instable metal flow easily occurs during the forming of thin-walled hollow components due to inappropriate control of forming load in conventional forming processes, thereby leading to forming failure.
