Dynamic nanoindentation testing: is there an influence on a material’s hardness?
Materials Research Letters, 2017 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 ...

To the Problem of Hardness Coating Determination with the Help of Dynamic Indentation Method
Наука и техника, 2003 Theoretical evaluation of a scale factor influence on thermal (depending on deformation rate) and athermanous (quasi-static) hardness components in dynamic indentation has been made.

Dynamics of Uniaxial Hard Ellipsoids [PDF]
Physical Review Letters, 2007 We study the dynamics of monodisperse hard ellipsoids via a new event-driven molecular dynamics algorithm as a function of volume fraction $ϕ$ and aspect ratio $X_0$. We evaluate the translational $D_{trans}$ and the rotational $D_{rot}$ diffusion coefficient and the associated isodiffusivity lines in the $ϕ-X_0$ plane.

The hardness of quantum spin dynamics
CoRR, 2023 Recent experiments demonstrated quantum computational advantage in random circuit sampling and Gaussian boson sampling. However, it is unclear whether these experiments can lead to practical applications even after considerable research effort. On the other hand, simulating the quantum coherent dynamics of interacting spins has been considered as a ...

Simulation of the dynamics of hard ellipsoids [PDF]
Philosophical Magazine, 2008 We study a system of uniaxial hard ellipsoids by molecular dynamics simulations, changing both the aspect-ratio X0 and the packing fraction PHI. We calculate the translational and rotational mean squared displacements, the translational and the rotational diffusion coefficients and the associated isodiffusivity lines in the PHI-X0 plane.

Hard-Sphere-like Dynamics in a Non-Hard-Sphere Liquid [PDF]
Physical Review Letters, 2005 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]
Physical Review E, 2014 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,
