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,

New instrumentation and analysis methodology for nano-impact testing
Materials & Design, 2020 The nano-impact test is a technique for high strain rate mechanical characterization of materials at the nano/microscale. However, its use has been limited so far due to the lack of appropriate methods to determine the dynamic hardness under impact ...

Hardness identification of rock based on multi-sensor information fusion during the process of roadway tunnelling [PDF]
Bulletin of the Polish Academy of Sciences: Technical Sciences, 2020 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.

Recovery Mechanisms in a Compressed Ni-Ti Superelastic Alloy [PDF]
Materials Research, 2017 The present work studied the influence of annealing on a Ni-Ti alloy submitted to uniaxial compression. The stress-strain curve under compression showed the absence of the Stress-Induced-Martensite (SIM) plateau and 42% of remaining austenitic phase (B2).

Impact Indentation of Metals at the Small Elastoplastic Strain
Механика машин, механизмов и материалов, 2022 The aim of this paper is to study and describe the behavior features of metals under impact loading in the area of elastic-plastic transition, with strains not exceeding 3–4 %, which are typical for measuring the hardness of materials during dynamic ...
