This paper puts forward the vital findings and scientific principles for the design and development of a digital material tensile strength analyser by the electrical resistivity per unit area technique for use in future undertakings. The metals used in this study are high tensile steel, low tensile steel and stainless steel of marine grade. The measurements made use of the standard ohm-meter or electrical resistivity meter. The measurement of the resistance per length between the probes of the materials is used to mathematically model the tensile strength, in particular the initial yield stress. The measurements were carried out using a normal resistivity meter or ohm-meter to measure the characteristics of the resistance per unit length (R/L) and will be related to the material strength, in particular the initial yield stress. Essentially, the measurements were performed non-destructively or by a non-destructive method. The results obtained were made to correspond to the actual tensile strength values of the materials being studied and expressed mathematically and graphically.
