The 2D Rousselier model, the Gurson-Tvergaard-\u003c\/div\u003e\u003cdiv\u003eNeedleman (GTN) model and the cohesive zone model (CZM) were\u003c\/div\u003e\u003cdiv\u003eadopted to predict the crack propagation of thick compact tension (CT)\u003c\/div\u003e\u003cdiv\u003especimens. Advantages and disadvantages of the three mentioned models\u003c\/div\u003e\u003cdiv\u003eare discussed. The cohesive zone model is suggested as it is easy to use\u003c\/div\u003e\u003cdiv\u003efor scientists \u0026amp; engineers because the CZM has less model parameters\u003c\/div\u003e\u003cdiv\u003eand can be used to simulate arbitrary crack propagation. The results\u003c\/div\u003e\u003cdiv\u003eshown in this thesis help to evaluate the fracture behavior of a metallic\u003c\/div\u003e\u003cdiv\u003ematerial. A 3D optical deformation measurement system (ARAMIS) and\u003c\/div\u003ethe synchrotron radiation-computed laminography (SRCL) technique\u003cdiv\u003ereveal for the first time the damage evolution on the surfaceof the sample\u003c\/div\u003e\u003cdiv\u003eand inside a thin sheet specimen obtained from steel S355. Damage\u003c\/div\u003e\u003cdiv\u003eevolution by void initiation, growth and coalescence are visualized in\u003c\/div\u003e\u003cdiv\u003e2D and 3D laminographic images. Two fracture types, i.e., a flat crack\u003c\/div\u003e\u003cdiv\u003epropagation originated from void initiation, growth and coalescence\u003c\/div\u003e\u003cdiv\u003eand a shear coalescence mechanism are visualized in 2D and 3D images\u003c\/div\u003e\u003cdiv\u003eof laminographic data, showing the complexity of real fracture. In\u003c\/div\u003e\u003cdiv\u003ethe dissertation, the 3D Rousselier model is applied for the first time\u003c\/div\u003e\u003cdiv\u003esuccessfully to predict different microcrack shapes before shear cracks\u003c\/div\u003e\u003cdiv\u003earise by defining the finite elements in front of the initial notch with\u003c\/div\u003e\u003cdiv\u003einhomogeneous f0-values. The influence of the distribution of inclusions\u003c\/div\u003e\u003cdiv\u003eon the fracture shape is also discussed. For the analyzed material, a\u003c\/div\u003e\u003cdiv\u003ehomogeneous distribution of particles in the material provides the\u003c\/div\u003e\u003cdiv\u003ehighest resistance to fracture.\u003c\/div\u003e\u003cp\u003e\u003c\/p\u003e \u003ch3\u003eDetails\u003c\/h3\u003e \u003cp\u003ePublished by: Springer\u003c\/p\u003e \u003cp\u003ePublication Date: 2018-09-01\u003c\/p\u003e \u003cp\u003eFormat: Paperback\u003c\/p\u003e \u003cp\u003eISBN-13: 9783319884059\u003c\/p\u003e \u003cp\u003eDOI: 10.1007\/978-3-319-67277-9\u003c\/p\u003e \u003cp\u003eDimensions: 235cm x155cm\u003c\/p\u003e \u003cp\u003ePages: 171\u003c\/p\u003e ","brand":"Springer International Publishing","offers":[{"title":"Default Title","offer_id":46266246004876,"sku":"9783319884059","price":98.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/9545\/1788\/files\/9783319884059.jpg?v=1770816757","url":"https:\/\/fh90cf-fv.myshopify.com\/products\/9783319884059","provider":"Late Knight Books and Services, LLC","version":"1.0","type":"link"}
