Numerical Simulations of Ductile Fracture in Steel Angle Tension Members Connected with Bolts
The aim of the paper is to verify and present methodology for ultimate tensile resistance prediction in steel angle tension members connected to gusset plates with one row of bolts. After a description of the experimental investigations, the next step was to build numerical models. The subjects of the experiments consisted of single plate specimens with drilled holes and angles connected to gusset plates with 1, 2, 3, or 4 bolts. Close attention was given to choosing the appropriate material model, which takes into account the influence of microstructural damage and the process of ductile fracture initiation and propagation. The porous Gurson-Tvergaard-Needleman material model was analysed and the paper focuses on hierarchical validation of numerical models of steel angle bolted connections, which will then be used for parametric studies.
