Unnotched and notched cylinders in split tension are analyzed. The load-distributed width has been shown to affect the stress and displacement distributions. Based on finite element analysis, linear elastic fracture mechanics (LEFM) formulas for the stress intensity factor KI, crack mouth opening displacement (CMOD), and the crack opening displacement (COD) profile for the split tension of notched cylinders are first provided in terms of load-distributed width as well as load magnitude, specimen size, and notch length. A formula expressing the effect of load-distributed width on maximum tensile stress in an unnotched cylinder is also provided.
