Web2 days ago · For static applications, the yield strength is the more important design constraint as per industry standard design practices; however, the ultimate strength can be useful for certain applications that call for it. 6061 aluminum alloy has a yield tensile strength of 276 MPa (40000 psi), and an ultimate tensile strength of 310 MPa (45000 psi). WebSep 2, 2024 · The area up to the yield point is termed the modulus of resilience, and the total area up to fracture is termed the modulus of toughness; these are shown in Figure 13. The term “modulus” is used because the units of strain energy per unit volume are \(N-m/m^3\) or \(N/m^2\), which are the same as stress or modulus of elasticity.
