| Abstract: | Cantilever steel beams of uniform strength
are having various industrial applications. In particular when it is used as leaf spring it undergoes very large deflection in comparison to beam of uniform cross section. The damage occurs in these beams mainly due to fatigue loading. Early detection of damage in such type of beams is very essential to avoid a major failure or accident. In this paper, firstly formulation
of an objective function for the genetic search
optimization procedure along with the residual force method are presented for the identification of macroscopic structural damage in an uniform strength beam.Two cases have been investigated here. In the first case the width is varied keeping the strength of beam uniform
throughout and in the second case both width and Cantilever steel beams of uniform strength
are having various industrial applications. In particular when it is used as leaf spring it undergoes very large deflection in comparison to beam of uniform cross se... |
