  2. 1. On the hot crack formation during solidification of iron-base alloys

    Author : Karin Hansson; KTH; []
    Keywords : hot cracking; hot tearing; cracking fracturing ; tearing; ductility; brittleness; embrittlement; fractures; ductile brittle transition; solidification; iron; copper; nickel; Invar; steels; free machining steels; stainless steels; penetration; crack;

    Abstract : Hot cracking during solidification is a severe problem inmany casting processes, for example in continuous casting.Combinations of low strength and low ductility of the materialat high temperatures and applied tensile stress can cause hotcracking. READ MORE

  4. 2. Numerical methods and multi-scale modeling for phase-field fracture - With applications in linear elastic and poro-elastic media

    Author : Ritukesh Bharali; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; fracture; multiphysics; finite element; multiscale; desiccation; solvers; fracking; phase-field; solution techniques;

    Abstract : This thesis presents novel numerical methods and a multi-scale modelling framework tailored for advancing the phase-field fracture model with applications in linear elastic and poro-elastic media. In the realm of the numerical methods, the focus lies on devising computationally efficient and robust monolithic solution techniques. READ MORE
