WebI'm trying to get the compressive strength (and Young's modulus) of a clay sample. The method I found is called 'Unconfined Compressive Strength of Cohesive Soil'. According to ASTM D2166M, I have to set the loading rate to 0.5-2%/min (axial strain). The machine I have though, is stress-controlled. It measures the load in Pa/s. WebMar 19, 2024 · Wiki says that "ideally" (emphasis added), flexural modulus should match Young's modulus, but as related to most polymers, IT DOES NOT. Generally, Young's is used for metals, which deflect (stress) and instantaneously spring-back (strain) when the load is removed, which is elastic. Most polymers are viscoelastic, except PTFE (teflon), …

Perhaps the authors mean "pure metals," but this too is incorrect. Many alloys are stiffer than many pure metals. "More elastic" is ambiguous, and the insistence that the meaning is always "stiffer" does not reflect any consensus in the field.
WebJun 6, 2024 · F = Y (∆L/L0)A. In this equation, F is equal to the force applied to the structure, Y is the Young's modulus for the material, ΔL is the change in length of the material when the force is applied to it, L0 is the initial length, and A is the cross-sectional area of the material. Example Young's modulus for some different materials: Webwhere C11 is Young’s modulus. Since xx du dx ε= , this leads to the wave equation x x+dx u F(x) F(x+dx) A .
