Stress-strain curves
WebJul 18, 2024 · We can notice the strain softening behaviour of concrete once the curve reaches its peak at 𝜀𝑐1. 𝜀𝑐1 is the compressive strain at maximum stress. 𝜀𝑐1 gets bigger as the concrete grade increases. In other words, higher grade concrete will be able to undergo larger strain before it starts to soften. Strain softening happens to ... WebSep 12, 2024 · Young's modulus: E = σ/ε. in which σ = stress and ε = extensional strain. The extensional strain is just the strain observed by stretching the material. In the graph shown above, Young's modulus is around: 250 Pa / 0.1 = 2,500 Pa. This initial region of the curve, in which Hooke's Law is obeyed, is sometimes called the "linear elastic region".

Now if you enter the point1 in the workspace, then it will show the corresponding stress and strain value. Let the stress and strain at point1 be y1 and x1, similarily for point2 stress and strain be y2 and x2.
WebSep 16, 2015 · The stiffness-strain plot uses the same data as the stress-strain curve, but for the clearest representation, engineers might need to use an expanded scale.

WebThe parameters, which are used to describe the stress-strain curve of a metal, are the tensile strength, yield strength or yield point, percent elongation, and reduction of area. The first two are strength parameters; the last two indicate ductility. The general shape of the engineering stress-strain curve (Fig. 1) requires further explanation. WebHookes law tells us that the stress is proportional to strain but you can only use this within the elastic limit so the natural question now is what happens when we go beyond the …
