Numerical study on plastic instability of circular bending deformation during rotational straightening of thin-walled tubing

The rotation straightening process achieves axis alignment by repeatedly bending the pipe material. For thick-walled aluminum alloy pipes with a large diameter-to-thickness ratio, under cyclic bending loads, they are prone to axial wrinkling-type plastic buckling instability on the compressed side, which severely degra...

Numerical simulation study on plastic buckling of thin-walled aluminum alloy tubing under cyclic bending

The 6061-T6 thin-walled tube material is prone to cyclic plastic buckling failure during rotational straightening and reciprocating bending service. In actual rotational straightening production lines and long-term reciprocating bending service, the tube bears repeated alternating positive/negative bending curvature lo...
