| Abstract: | The condition, on which concrete specimens have been steady cracked under uniaxial tensile loading, are discussed based on the energy theory. According to the authors' and other researches, the requirements for set up and measurement in dynamic tensile test of concrete are analyzed. The suitability of three test methods including uniaxial tension, splitting tension and flexure test method for concrete test under dynamic tension are also analyzed. Based on the above analyses, a new test method for concrete under dynamic tension is suggested. |
