WebMar 14, 2024 · The elastic modulus was obtained from the linear portion of the monotonic curve through linear regression, whereas the initial yield stress was estimated by considering a plastic strain offset of 0.0025%, the same value adopted in Zhou et al. 43 The estimated values for each test were used to calculate the mean, standard deviation, and ... WebOn a stress/strain curve, the elastic region is generally depicted as the portion of the curve with a constant slope. Yield can be measured in several different ways depending on the type of material and type of test being performed ( tension, compression, etc).
WebTensile and Microindentation Stress-Strain Curves of Al-6061 Weaver, Jordan S.; Khosravani, Ali; Castillo, Andrew; Kalidindi, Surya R. Recent spherical microindentation stress-strain protocols were developed and validated on Al-6061 (DOI: 10.1186/s40192-016-0054-3). The scaling factor between the uniaxial yield strength and the indentation ... Webjected to a constant static load, it deforms immediately to a strain predicted by the stress–strain modulus determined from the tensile stress–strain curve. The material continues to deform indefinitely at an ever decreasing rate. If the load is high enough, the material may yield or rupture. This time-dependent viscous flow component of
