Explanation of stress strain curve
WebThe engineering stress-strain curve drops after the ultimate strength is reached because the force that can be supported by the material drops as it begins to neck down. However, the stress value in the true stress-strain curve always increases as the strain increases. 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 elastic limit I mean we know the proportionality won't work anymore but what happens to the material and that's what we're going to explore in this video and so before …

WebThe shear modulus is the proportionality constant in Equation 12.33 and is defined by the ratio of stress to strain. Shear modulus is commonly denoted by S: 12.43. Figure 12.24 An object under shear stress: Two antiparallel forces of equal magnitude are applied tangentially to opposite parallel surfaces of the object. WebThe stress–strain curve is the most reliable and complete source for the evaluation of mechanical properties of any fibre. The stress–strain curve is produced by plotting the applied stress on the fibre axis and the elongation produced due it. The stress–strain curve of a model fibre is shown in Fig. 3.1.
