Optimization algorithm and the inverse problems applied to the structural damage identification in steel beams with the use of fem and experimental data

Autor: Brunno Emidio Sobrinho, Gilberto Gomes, Ramon Saleno Yure Rubim Costa Silva, Welington Vital da Silva

Optimization problems are recurrent both in academia and in industry, in addition, the conditions of structural elements throughout their useful life when in use tend to acquire different damages arising from their natural deterioration or even due t
