Abstract

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 K_I, 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.
