Dynamic nanoindentation testing: is there an influence on a material’s hardness?
Modern nanoindentation devices are capable of dynamic experimentations, which allow us to exploit instrumented hardness tests extensively. Beside the assets of recording mechanical properties continuously over displacement, there are ongoing debates ...

Hard-Sphere-like Dynamics in a Non-Hard-Sphere Liquid [PDF]
The collective dynamics of liquid Gallium close to the melting point has been studied using Inelastic X-ray Scattering to probe lengthscales smaller than the size of the first coordination shell. %(momentum transfers, $Q$, $>$15 nm$^{-1}$). Although the structural properties of this partially covalent liquid strongly deviate from a simple hard ...

Escape dynamics of many hard disks [PDF]
Many-particle effects in escapes of hard disks from a square box via a hole are discussed in a viewpoint of dynamical systems. Starting from $N$ disks in the box at the initial time, we calculate the probability $P_{n}(t)$ for at least $n$ disks to remain inside the box at time $t$ for $n=1,2,\cdots,N$. At early times the probabilities $P_{n}(t)$, $n=2,

Hardness identification of rock based on multi-sensor information fusion during the process of roadway tunnelling [PDF]
In this paper, a new dynamic model was proposed for identifying the rock hardness during the process of roadway tunnelling, thereby regulating the speed of the driving motor and the torque of the cutting head.
