6. The nominal critical shear stress in a weld metal is calculated to fluctuate be tween -3 ksi and i (i.e. fully reversed stress). A stress concentration factor is consistent with the "End of parallel fillet weld". The weld electrode is E100. The weld surface is similar to a Hot Rolled surface. What is the factor of safety guarding against eventual fatigue failure for the weld metal? b) 1.92 a) 1.55 d) 2.94 c) 2.46 e) None of these 6....
Question 1 (30 Marks) Plate A is fillet-welded to Plate B as shown in Figure 1. Plate A and Plate B have the same material properties Both plates are 10 mm thick. There are two holes (with a diameter of d) in Plate A. It is assumed that weld failure will not occur (a) If Plate A has a yield stress (fy) of 350 MPa and an ultimate tensile strength (fu) of 450 MPa, what is the maximum load (P)...
Question 3 (20 marks) Two 304 stainless steel plates are welded together at their ends as shown. During operation, the plates are exposed to a wet chloride environment and subjected to tensile forces as shown in Figure Q3. After a period of time, the plates are found to have failed at the weld joint as a result of stress corrosion cracking. weld 304 stainless steel plate 304 stainless steel plate applied force applied force Figure Q3 (a) Explain what is...
