| 描述 | In this thesis, the author investigates experimentally and numerically.the fracture behavior of an electron beam welded joint made from.two butt S355 plates. The 2D Rousselier model, the Gurson-Tvergaard-.Needleman (GTN) model and the cohesive zone model (CZM) were.adopted to predict the crack propagation of thick compact tension (CT).specimens. Advantages and disadvantages of the three mentioned models.are discussed. The cohesive zone model is suggested as it is easy to use.for scientists & engineers because the CZM has less model parameters.and can be used to simulate arbitrary crack propagation. The results.shown in this thesis help to evaluate the fracture behavior of a metallic.material. A 3D optical deformation measurement system (ARAMIS) and.the synchrotron radiation-computed laminography (SRCL) techniquereveal for the first time the damage evolution on the surfaceof the sample.and inside a thin sheet specimen obtained from steel S355. Damage.evolution by void initiation, growth and coalescence are visualized in.2D and 3D laminographic images. Two fracture types, i.e., a flat crack.propagation originated from void initiation, growth and coalescence.and a shear coalescence me |
