Deformation Characteristics of Concrete under Uniaxial Compression

Depth study of deformation characteristics of concrete can reveal failure mechanism of concrete materials based on strain. This paper studies the deformation characteristics of concrete under uniaxial compression, and draw conclusions that deformation can cause the expansion of internal micro cracks, in accordance with the expansion of micro cracks, the law of cracks development of concrete under uniaxial loads is divided into three stages, micro-cracks relatively stable, stable crack development period and unstable crack development period. The research results can provide valuable reference for future research work.
