FEACaseStudyFatigue

SmallLHArrow What do the FEA numbers actually mean? (FEA Fatigue & durability) SmallRHArrow

FEA Fatigue Damage and Tolerance: Or durability. From empirical test data, SN curves (stress to number of cycles to failure) are generated. For LM9 cast aluminium alloy, a tensile stress of 90MPa is generated to undergo 2x10^7 cycles (20 million). This is a reasonable duty cycle for a wheel and it means that 20 million cycles @90MPa maybe performed before the wheel fails. Fatigue damage and tolerance (FDT) and SN curves give us the actual stress numbers we need to design for. If you are finding that parts are breaking prematurely (before the duty cycle is complete), then it could be a part stress problem, a manufacturing defect causing weakness, residual stresses or non-homogeneity of the material. It's not intuitive, hence we'll try and help you with any issues you may have.
