Hello everyone, I have designed a part that should be able to withstand a shear stress of 43 MPa ( give or take). The part will be made of Nickel Aluminum Bronze (CuAl10Ni5Fe4). When I check yield strength values for this material (I'll multiply it by 0.6 to estimate its shear strength), they are in general given in 0.5% extension under load yield strength. I am not familiar with this, I always used 0.2% elongation yield strength. How should I proceed in this case? It is given as 290 MPa. I've researched it a bit, it seems that 0.5% extension under load y ield strength is given when the other one is difficult to measure, but didn't find much else.
