Mechanical Properties of Limestone After High
2021-9-6 High temperatures can cause deterioration of the physical–mechanical properties of rocks. In this study, the triaxial cyclic loading and unloading of rock specimens under different temperature conditions were investigated to reveal stress–strain curves, strength and deformation characteristics, failure forms, and peak stress dropping of the rock specimens at high temperatures. The ...

Study on the Dynamic Mechanical Properties of
In order to study the dynamic mechanical properties of metamorphic limestone under different strain rates, a reasonable impact air pressure must be determined before the impact test. Different impact air pressures are used to achieve different impact speeds of bullets to analyze the failure of rock specimens under different strain loading rates.
