In this paper J integral of Al 6075 T6 was computed through experimentally performing the compact tension (CT) specimen test in which stress intensity factor and J-integral parameters are calculated by CT test. The fracture toughness criterion (CT samples) is choosing for calculating J-integral results. The results are also found through finite element analysis using Abaqus software and results are validated with experimental data which are much close to this. The fracture analysis is carried out using displacement boundary loading condition, considered for evaluating J integral at 3D contours obtained in the model.

摘要

In this paper J integral of Al 6075 T6 was computed through experimentally performing the compact tension (CT) specimen test in which stress intensity factor and J-integral parameters are calculated by CT test. The fracture toughness criterion (CT samples) is choosing for calculating J-integral results. The results are also found through finite element analysis using Abaqus software and results are validated with experimental data which are much close to this. The fracture analysis is carried out using displacement boundary loading condition, considered for evaluating J integral at 3D contours obtained in the model.
