WebSep 7, 2024 · Stress-strain curves often are not straight-line plots, indicating that the modulus is changing with the amount of strain. In this case the initial slope usually is used as the modulus, as is illustrated in the diagram at the right. Rigid materials, such as metals, have a high Young's modulus. In general, fibers have high Young's modulus values ...
WebMar 31, 2024 · The stress-strain curve is relevant to all specimens made from this material. The Load-extension curve is relevant to specimens with only one combination of L and A. So if you take a specimen with double the thickness, then the Force-extension diagram will change. (the force will double for the same displacement). However the …
