This paper outlines the results of experimental study dynamic rock failure based on comparison dry and saturated limestone samples obtained during compression split tests. The tests were performed using Kolsky method its modifications for splitting. mechanical data (e.g. strength, time energy characteristics) this material at high strain rates are obtained. It is shown that these characteristics sensitive to rate. A unified interpretation rate effects, structural–temporal approach, hereby...
The acoustic cavitation of fluids, as well related physical and chemical phenomena, causes a variety effects that are highly important in technological processes medicine. Therefore, it is to be able control the conditions allow begin progress. However, accurate prediction dependent on complex relationship between external influence parameters fluid characteristics. multiparameter problem restricts development successful theoretical models. As result, critical identify most influencing onset...
Nickel matrix composites are important materials for various engineering applications. The present paper describes the fabrication of bulk graphene-nickel (Gr-Ni) and reduced graphene oxide-nickel (rGO-Ni) by powder metallurgy technique using sources, namely, thermally exfoliated graphite (TEFG) oxide (rGO) investigation mechanical properties composites. Homogeneous distribution derivatives in composite matrices was confirmed all compositions XRD Raman spectroscopy. It proved that different...
In recent years, additive manufacturing of products made from 5000 series alloys has grown in popularity for marine and automotive applications. this work, we compare mechanical properties characteristics aluminum alloy 5056 material produced by wire-arc technology rolling. We carried out tension tests under quasi-static loading impact toughness loading. The results show that upon similar ultimate tensile strength ductility, after demonstrates decreased resistance against dynamic than...
When we want to compare the strength of two materials, table values quasistatic strength. However results some experiments show that ratio materials can change with increase in rate loading. Such "substitution effect" material at different strain rates is studied this paper. It shown one have a lower dynamic for higher static compared other material. Tests tests mortar and concrete, concrete water content are considered. load-carrying capacity substitution effect wide range loading be...
The results of dynamic compression and splitting dry water-saturated limestone are presented. tests have been performed using the Kolsky method its modification for splitting. strength fracture time this material at high strain rates obtained. It is shown that these characteristics sensitive to rate. A unified interpretation rate effects based on incubation approach Theoretical calculations show application concept allows select optimal ratio duration amplitude action, which can reduce...
