【 摘 要 】

The explosion rate is increasing in marine and industrial field. This paper investigates the confined blast response of steel square plates stiffened with diagonally biased plate stiffeners. ANSYS Autodyn was used to conduct the parametric study and to analyze the effect of these diagonally biased stiffener plates on structural response and failure of these plates. Furthermore, a study on the plastic behavior and failure of these high strength steel plates due to the impact of blast waves were conducted. Among the explosives available, TNT is used as the charge mass.
