UTS or we can say Ultimate Tensile stress is the maximumstress that can be calculated in order to know the limit of stress bore by the material. The formulafor UTS is the force exerted per unit area. =For calculating the Fracture stress we know that it is the point where the stretching orpulling of material fails and results in permanent deformation or breakage. Studies also show thatFracture stress is equal to UTS.FS=UTSFor calculating the percentage elongation or ductility of a material, we divide thespecimen length for maximum elongation by the initial length (specimen).Percentage elongation= Lx-Lo/L0= For calculation of the Percentage reduction area, we use this formula:= ...
