During a high cycle fatigue test, a metallic specimen is subjected to cyclic loading with a mean
stress of +140 MPa, and a minimum stress of -70 MPa. The R-ratio (minimum stress to
maximum stress) for this cyclic loading is
(round off to one decimal place)
4. A stainless-steel slab having a edge crack of length 5 mm is subjected to a stress of 375 MPa. According to Irwin’s model, the length of effective plastic zone in front ahead of crack tip in plane strain condition is ________ mm.
5. The stainless-steel slab in the above problem is replaced by a thin stainless-steel plate and was subjected to similar loading condition. The length of total plastic zone ahead of a 5mm edge crack is r1. Considering the length of the plastic zone in the above problem is r2, the value of r2/r1 is ____.
Is the maximum shear stress theory is based on the idea of slipping that occurs in ductile failure?

The maximum tensile stress was specified as 30% of the yield stress (0₂ = 300 MPa) and the stress ratio R was zero. Post-failure examination found that fatigue crack growth striation started at a depth of 2.0 cm from the surface, and the striation spacing was 1.3 x 10-4 cm. The fatigue-crack growth behavior of the aluminum alloy is given in the right figure. The manufacturer claimed that the part was overloaded by the user, but the user denied the allegation and sued the manufacturer.
