Determination of manufacturing residual stresses in cold-formed thin-walled steel profiles

Experimental study on high‐cycle fatigue performance of cold‐rolled steel sheet connections using self‐tapping screws and blind rivets

“…Currently, most studies on the fatigue performance of cold‐formed, thin‐walled steel structures have focused on the fatigue failure of shelves and rails employed in the logistics industry. These studies primarily explored the impact of cold bending on the profiles 7,8 . Additionally, some researchers 9–12 investigated the wind‐induced fatigue failure of roof panels connected by self‐tapping screws.…”

Numerical Simulation and Experimental Study of Cold and Hot Composite Forming of Sharp-Edged High-Strength Steel Sections

“…Phenomena like cracking at the corners [8,9] and thickness reduction [10] can also occur. Plastic deformation can also arise at the crossroads during roll forming [11,12], leading to strain hardening [13] and residual stress in the material [14,15], thereby affecting the performance of the steel sections [16,17]. The bending radius can only be increased to avoid defects in the bending zone of high-strength steel forming [18], which affects its range of use in later stages.…”
