4/6/2024 0 Comments Calculate fatigue strengthġ) 'Linear' is generally regarded as most suitable for high-cycle/low-stress (range) applications, andĢ) 'Non-Linear' is generally considered most suitable for components with an operational life comprising large stress ranges and large cyclic variations. Of the two statistical calculation methods available in Fatigue. Important: You should only use principal stresses (see CalQlata's Combined Stress) in fatigue calculations, not primary stresses, because principal stresses include the effects of shear. The metal fatigue calculator includes statistical comparisons of predicted or available stress cycles with base-line or allowable stresses, and assessment according to Goodman's non-zero/mean. You simply calculate the limiting design stresses under various operational conditions and then compare the number of these stresses with known performance characteristics for the material, which Fatigue will do for you. You shouldn't be deterred from attempting metal fatigue calculations simply because it's a procedure with which you are unfamiliar it's not as complicated as you might think.
