摘要：
A method based on measurements of axial and transverse strains was developed for evaluation of the extent of microcracking in prismatic concrete specimens under uniaxial compression. The increase in the area of crack per unit cross-sectional area, which has the units of strain, was estimated from the transverse and axial strain measurements using a simple formula which involves the elastic Poisson's ratio, determined a priori from the strain data.
