Physics of martial arts: Incorporation of angular momentum to model body motion and strikes.
We develop a physics-based kinematic model of martial arts movements incorporating rotation and angular momentum, extending prior analyses. Here, our approach is designed for a classroom environment; we begin with a warm-up exercise introducing counter ...

Modeling the real contact area plays a key role in every tribological process, such as friction, adhesion, and wear. Contact between two solids does not necessarily occur everywhere within the apparent contact area.

Slip and Friction Mechanisms at Polymer Semi-Dilute Solutions/Solid Interfaces [PDF]
The role of the polymer volume fraction, $ϕ$, on steady state slippage and interfacial friction is investigated for a semi-dilute polystyrene solutions in diethyl phthalate in contact with two solid surfaces. Signicant slippage is evidenced for all samples, with slip lengths b obeying a power law dependence.

Process mechanics in continuous friction stir extrusion process of aluminum alloy
. Friction Stir Extrusion (FSE) is an innovative direct-recycling technology developed for metal machining chips. A rotating die is plunged into a cylindrical chamber containing the material to be recycled during the procedure.

In the friction stir welding process, the tool role in the material flow and its thermomechanical behavior is still not entirely understood. Several modeling approaches attempted to explain the material and tool relationship, but to this date ...

A Mesh-Free Solid-Mechanics Approach for Simulating the Friction Stir-Welding Process
In this chapter, we describe the development of a new approach to simulate the friction stir-welding (FSW) process using a solid-mechanics formulation of a mesh-free Lagrangian method called smoothed particle hydrodynamics (SPH).
