ANALYSIS OF THE 3-DIMENSIONAL STRESS DISTRIBUTIONS OF COLD STRIP ROLLING UNDER LARGE WIDTH TO THICKNESS RATIO BY SPLINE FINITE STRIP METHOD

Under the width to thickness ratio 625 of strip,this paper studies the 3-dimensional stress distributions of cold strip rolling by cubic spline function finite strip method.The distributions of the stresses are obtanied in 2 cases of edge wave and center wave of rolled strip.This paper Is of impertance to the shape theory and the shape control.
