Rupture and dynamic hardness of ice

Doklady Physics, 2004
Imperfection of the available tension procedure is associated with the appearance of the bending moment, stress concentrations at the fastening points of samples, and initial slackness of loading systems. These factors are responsible for the distortion of the tension diagram even in its initial section [2, 3].

Dynamics of hard sphere suspensions

Physica A: Statistical Mechanics and its Applications, 1990
Abstract We consider a dispersion of solid spherical particles in an incompressible viscous fluid, and study the dynamics of this two-phase system on the basis of linear response theory. We start from a rest situation, in which the spheres are assumed to be distributed in a disordered configuration.

Dynamic Indentation Hardness of Metals

2006
An experimental technique for determining the dynamic indentation hardness of materials is described. Unlike the traditional static hardness measurements, the dynamic hardness measurements can capture the inherent rate dependent material response that is germane to high strain rate deformation processes such as high speed machining and impact.

Dynamic Hardness Testing Procedures

2007
IN DYNAMIC HARDNESS TESTING PROCEDURES, THE INDENTER HITS the specimen surface with impact. The specimen material can thereby be elastically and unelastically deformed. Deformation that arises due to the kinetic energy of the indenter and remains can be measured.
