A horizontal steel plate is welded on 3 sides to a rigid steel frame (vertical plate) as shown below with 8 mm fillet using E100xx electrode (S, = 600 MPa and St=689 MPa). A completely reversed load of 10 kN is applied at the mid-width point of the steel plate as shown below. Determine the factor of safety for a finite life of 500,000 cycles and 50% percent reliability. The analysis should account for appropriate stress concentration factor in fatigue at the weld as per the textbook. 30 4100 .200 50 A horizontal steel plate is welded on 3 sides to a rigid steel frame (vertical plate) as shown below with 8 mm fillet using E100xx electrode (S, = 600 MPa and St=689 MPa).
