Abstract

Abstract

The finite strip method in structural analysis has been extended,and elastic-plastic large deformation spline finite strip method based on the Updated-Lagrange method(U.L.method)was established to simulate roll forming process of channel section with outer edge.The deformation characteristics of strip was analyzed,and the three dimensional displacement field,strain field and stress field of deformed strip were got.The calculation example proves that the peak transverse pressing membrane strain is on the corner part of the deformed strip,and the peak longitudinal stretching strain is on the outer edge part of the deformed strip in front of rolls.In addition,the transverse deformation of the deformed strip is principal,and the longitudinal deformation is small.
