Abstract
ABSTRACT
Finite element analysis is extensively employed to predict the structural response of
mechanical components so reducing costs of experimental programs. However,
among other aspects, the accuracy of the input material parameters in the finite
element modeling strongly determines the simulation accuracy. The aim of this study
is to evaluate the material constitutive parameters, considering an elasto plastic
material model with strain rate sensitivity and failure and by using an inverse
methodology. The evaluated material was a mild steel sheet used in scale models of
naval structures. Quasi static and dynamic tests were performed and the so obtained
material parameters were corroborated through numerical modelings of notched and
shear specimens tests. Finally, a discussion about the evaluation of strain rate
sensitivity model and failure criteria parameters is also presented.
