摘要: Abstract This paper focuses on the study of influence indentation parameters ultimate strength and behavior damaged panels for two types stiffeners, through an experimental-numerical correlation a parametric study. Experiments were performed using stiffened in small-scale models, with stiffener type T flat-bar, representing typical full-scale bottom deck ship, respectively. A series tests have been carried out plate-stiffener intersection where force displacement pattern are analyzed each stiffener. After indentation, panel model is submitted to uniaxial compression test, order measure loss relation intact one. Numerical simulations by finite element program both collapse. The results from numerical-experimental presented good agreement. Therefore, analyze parameters, such as, dent depth, indenter size, location column slenderness. research work contributes better understanding define more robust safe design bases, as well support decision repair procedures.
