Accurate tensile characterization of structural materials is critical for construction safety, technical standardization, and civil liability in the event of structural failures. Diametral compression testing, based on the formulation by Hondros (1959), is widely used to estimate indirect tensile strength under linear elastic assumptions. However, when applied to ductile structural steels, elastoplastic stress redistribution significantly alters the internal stress field, potentially leading to overestimation of effective tensile strength This study critically examines these limitations from a technical–legal perspective, demonstrating how uncritical use of purely elastic formulations can affect regulatory compliance and professional liability. A plastically corrected factor is proposed to align experimental practice, mechanical reality, and legal safety.
