WebDownload scientific diagram Stress-strain curve of gold thin films, showing non-linearity at low loads. The dashed line is fitted to the curve to find the zero point. WebOct 13, 2024 · This is a cool idea. I think it is pretty straightforward, although I don't have any experience with image processing. So the basic idea, is you have data of stress vs strain, and you know that Hooke's law describes the behaviour during the linear portion of the curve (before plastic deformation occurs).

WebA typical stress-strain curve for the cyclic uniaxial compression on rock is shown in Fig. 2 where H p, H e, and H t represent plastic, elastic and total static strain respectively and EN p and EN e represent plastic and elastic strain energy respectively.

WebOften, this value is significantly more than the yield stress (as much as 50 to 60 percent more than the yield for some types of metals). When a ductile material reaches its ultimate strength, it experiences necking where the cross-sectional area reduces locally. The stress-strain curve contains no higher stress than the ultimate strength. Web63 rows · The highest point of the stress–strain curve is the ultimate tensile strength and has units of stress. The equivalent point for the case of compression, instead of tension, is called the compressive strength . …
