Researches into Mechanical Properties of Rocks under Dynamic (Cyclic) Loading.

Popis výsledku v původním jazyce

Researches into mechanical properties of rocks are mostly done under static (quasistatic) loading. In nature, however, rocks are also often subjected to dynamic (vibration) loading as a result of propagation of seismic waves due to e.g. earthquakes, rockbursts, blasting operations, etc. This type of loading can be simulated on a modern press, MTS 816 Rock Test System, purchased by VSB-Technical University of Ostrava. Whereas in the past, especially stress-strain and energy characteristics in the courseof dynamic (cyclic) loading were observed on this test system, recently research has focused mainly on the observation of rheological properties during this loading. In the course of observation of energy characteristics of mechanical loading, anomalieswere found before achieving the limit of ultimate strength. The cause of them is probably the action of energies other than mere mechanical energy. For this reason, research focused on the determination of temperature changes in the cours
