摘要：

The compliance calibration function for the clamped single-edge tension (SE(T)) specimen has not been reported in the literature. Based upon the inverse fitting of the three existing CMOD-based compliance equations, three CMOD-based compliance calibration equations are proposed for specimens with a crack length-to-width ratio 0.05 <= a/W <= 0.75. The fitting errors of the equations here employed are no greater than 1 %.
