摘要
Fifty longitudinal fillet welded lap joints with main plates (12 mm thick) and overlapping plates (8 mm thick) made of Q345B high-strength low-alloy structural steel, were tested. The joint specimens were fatigued at room and low temperatures (0 °C, −20 °C, and − 40 °C) under constant amplitude loading. The test life results were modelled by S–N curves and the crack growth was modelled in detail by applied fracture mechanics. The results show that the fatigue strength of the lap joint varies insignificantly when the temperature ranges from 20 °C to − 40 °C.
