Experimental investigation of residual stresses in roller bent wide flange steel sections

Out-of-plane stability of roller bent steel arches — An experimental investigation

“…Residual stress measurements by Spoorenberg et al [18] and tensile testing by Spoorenberg et al [25] have shown that both phenomena are present in a roller bent arch. It can be seen that for both arches, the strains measured at the crown remain within the elastic limit.…”

“…It is known that the roller bending process alters the residual stresses, mechanical properties and cross-sectional properties of the section. Residual stresses were measured in roller bent wide flange section by Spoorenberg et al [18]. The changes in crosssectional dimensions (flange widths, web height etc.)…”

Analytical Model of a Multi-Step Straightening Process for Linear Guideways Considering Neutral Axis Deviation

“…The measurement of residual stresses is mainly realized by destructive, semi-destructive, and non-destructive techniques. Based on a general classification, the measurement methods can be categorized as mechanical, optical, diffraction, and stress-relevant property methods [18]. Among these methods for measuring the residual stresses, the mechanical method by strain gauges is the most common one for measurement of residual stresses in stress analysis [19].…”

Study on mechanical behaviour of cold-formed steel channel pre cut-curving beam

“…The cold-curving of steel section also known as cold-bending or roller-bending is proposed by using the rollers and frequently utilised for curving arches [1]. The process of cold-curving is just positioned in the machine and moved through the three rolls to formed curved section in normal temperature [1].…”

“…The process of cold-curving is just positioned in the machine and moved through the three rolls to formed curved section in normal temperature [1]. This process only can be used for I section and closed section such as hollow and solid section.…”
