Sheet Metal Forming - University of Rhode Island
personal.egr.uri.eduBending Sheet Metal • In bending, outer fibers are in tension while inner fibers are in compression • Bend allowance is the length of the neutral axis in the bend, L b = a (R+kT) • k is a constant that ranges from 0.33 (for R<2T) to 0.5 (for R>2T) • Engineering strain during bending: • As R/T decreases, the tensile strain at outer fiber
