Dynamical study of a polydisperse hard-sphere system [PDF]
Physical Review E, 2010 We study the interplay between the fluid-crystal transition and the glass transition of elastic sphere system with polydispersity using nonequilibrium molecular dynamics simulations. It is found that the end point of the crystal-fluid transition line, which corresponds to the critical polydispersity above which the crystal state is unstable, is on the ...

Event-driven Brownian dynamics for hard spheres [PDF]
The Journal of Chemical Physics, 2007 Brownian dynamics algorithms integrate Langevin equations numerically and allow to probe long time scales in simulations. A common requirement for such algorithms is that interactions in the system should vary little during an integration time step; therefore, computational efficiency worsens as the interactions become steeper.

EVALUATION OF METALLIC MATERIALS PLASTICITY BY DYNAMIC INDENTATION METHOD
Литьë и металлургия, 2017 The method of plasticity test of metallic materials realized by means of a dynamic dimpling of material by a spherical tip is offered. The measured value of plasticity is defined by a ratio of plastic and complete deformations in the formed indentation ...

INVESTIGATION OF THE RATIO BETWEEN THE DYNAMIC AND STATIC HARDNESS OF METALS
Весці Нацыянальнай акадэміі навук Беларусі: Серыя фізіка-тэхнічных навук, 2017 Problems of measurement of hardness by the dynamic indentation method are discussed. It is shown that an excess of dynamic hardness over static one can be described by the coefficient, which is a function of material properties and test conditions.In ...
