Experimental study on residual stresses of dual phase high‐strength cold‐formed steel angles
The rapid advance in advanced high‐strength cold‐formed steel makes this material promising for the construction industry to use as structural framing, but necessitates an accurate understanding of mechanical properties, including residual stresses. An experimental study was conducted to measure the residual stress which is generated during the member manufacturing process of a press‐braked angle member composed of advanced high‐strength cold‐formed sheet steel. The amplitude and distribution of membrane and flexural residual stresses around the member cross‐section is presented and the magnitude of residual stresses relative to the yield strength for the test specimen and other previous studies are compared. Additionally, the cutoff length typically recommended for residual stress measurements is investigated by comparing the residual stress distribution around the cross‐section for a section taken from the center and near the end of the member.
