Using the strain-based Morrow fatigue equation (Combination of Coffin-Manson relation and Basquin relation) for combined LCF-HCF fatigue model, find the max allowable strain amplitude
Using the strain-based Morrow fatigue equation (Combination of Coffin-Manson relation and Basquin relation) for combined LCF-HCF fatigue model, find the max allowable strain amplitude for completely reversed (R = -1) cyclic loading that the following steel bars can endure, if they have to survive for Nf= 1250 cycles (Assume Young's modulus E = 200 GPa for all steels): a. SAE 1015 (of = 976 MPa; b = -0.14; & = 0.76; c= -0.59)
