Residual Stresses and Deflections in Complex Shapes Formed by Laser Bending.

Abstract

Previous quantitative results obtained at M.I.T. on the bending of steel by laser line heating to produce simple angular deflections have been verified and expanded. Deflections and residual stresses in compound shapes formed by laser line heating of steel are measured and analyzed. From the measured deflections, algorithms are developed allowing the construction of idealized compound shapes including the dish, saddle, cone, and sine. All algorithms are developed from single pass laser line heating data.
