The description of the test is followed by a discussion and comparison of the determination of the effective tensile strength of soil under a framework proposed in previous research. Test results reveal that, in general, tensile strength is proportional to indenter diameter (a) to specimen diameter ratio (b), a=b, and has no apparent relationship with the specimen height (H) to diameter ratio, H=2b. The iterative method provides a more realistic approach to compute the tensile stress beyond the traditional method. In addition, the iterated parameter, K, was found to be linearly related to the a=b ratio, for a given specimen, regardless of H=2b value. Finally, the effective tensile strength was verified by an indentation test in conjunction with the pressure plate test and consolidated undrained triaxial test under an unsaturated soil framework. © 2018 American Society of Civil Engineers.Effective tensile strengthIndentation testSuction stressUnsaturated soiljournal article10.1061/(ASCE)MT.1943-5533.00025702-s2.0-85055952863
