Abstract

The main purpose of this paper is to study the anisotropic
behavior of laser welded interstitial free steel HC 260Y when it is subjected
to monotonic tensile tests. The specimens were cut in different orientations
according to the rolling direction, annealed and finally assembled by laser
welding. The plastic behavior was modelled using an identification strategy
based on a behavior law taking into account the anisotropy of this material, a
hardening law describing the evolution of the hardening curves and an
evolution law. The proposed identification strategy allowed for a good
validation of the model. The model was afterwards used to predict the
behavior of the welded material when it is subjected to various solicitations.
Finally, the fracture surfaces of the specimens were examined using the
scanning electron microscope (SEM) to determine the failure characteristics
under the tensile loading.
