Test Bench to Study Complex Stress Evolution in Geomaterials under Weak Dynamic Loads

Аннотация

The test bench has been designed to subject specimens of geomaterials to loading by torsion and longitudinal compression with the simultaneous multiple weak impacting. The measurement system contains sensors for static and dynamic measurements of strains. The tests experiments included cyclic torsion of mixed gypsum and quartz sand specimen. The static and dynamic strains were measured, and the velocity of elastic wave in organic glass was determined.
