In order to obtain the post-peak stress–strain curve of plain concrete, the strain-controlled uniaxial tensile tests are carried out on cylindrical specimens. The tensile cyclic tests are performed between a lower compressive load and an upper load to the envelope curve. Test results have shown that residual strain accumulates slowly when the concrete is subjected to alternating tensile–compressive...
To research the fracture pattern of concrete specimens, the dynamic splitting tensile tests are conducted in different arc loading angles and impact velocities. The stress state of the specimens can be calculated by analyzing the strain gauges data on the split Hopkinson pressure bar. The specimens under the lower impact velocity achieves the stress equilibrium in loading direction, and the stress-state...
