FAILURE CRITERION FOR PLAIN CONCRETE UNDER SHORT-TIME LOAD

Considering plain concrete as an isotropic, homogeneous continuum, a criterion has been proposed to govern the failure of this material. According to this strain-based criterion, two modes of failure are possible, i.e., the material element may fail either in shear or in tension depending upon the corresponding strain (stress) state. It is shown in this paper that the proposed failure criterion is capable of predicting with great accuracy the experimental results obtained from two different types of test. Moreover, the theory may be applied to predict the mode of failure if the stress states of the samples are carefully controlled. A method has also been proposed for obtaining constant stress and strain states during unconfined compression tests.
