A damage-plasticity model for the dynamic failure of concrete
, 2011 A constitutive model based on the combination of damage mechanics and plasticity is developed to analyse concrete structures subjected to dynamic loading. The aim is to obtain a model, which requires input parameters with clear physical meanings.

The uniaxial compressive strength of concrete: revisited
Materials and StructuresAbstractThis paper re-examines common notions and conventions regarding the compressive strength of concrete in general and of the uniaxial compressive strength of concrete in particular. A distinction is introduced between the strength of the specimen and the strength of the concrete as a material, and the commonly measured and adopted strength is ...

Study on the size effect of rock burst tendency of red sandstone under uniaxial compression
Scientific ReportsThe study of rock burst tendency of rock masses with different sizes plays a key role in the prevention of rock burst. Through theoretical analysis, it is proposed that uniaxial compressive strength and deformation modulus ratio are the key mechanical ...

Estimation of uniaxial compressive strength from point load strength,
, 2008 Uniaxial compressive strength is considered one of the most important parameters in the characterization of rock material in rock engineering practice. The study investigated correlations between uniaxial compressive strength and point load index, P-wave velocity and Schmidt hardness rebound number together with the effects of core diameter size.

The influence of dry-wet cycle on the compressive strength of tuff
Discover Applied SciencesRainfall increases the moisture content of rocks, alters their internal structure, and weakens their mechanical strength, thereby compromising slope stability. Therefore, exploring the potential impact of rainfall on rock slopes is crucial. In the paper,
