1. 1. Crack propagation calculations in non-elastic metals

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Material- och solidmekanik

   Författare :Máren Ingá Baer; [2018]
   Nyckelord :crack propagation; fracture mechanics;

   Sammanfattning : It is important to know the lifespan of a component, thus services can be planed. At Siemens Industrial Turbomachinery AB (SIT AB) develop and produce gas and steam turbines, the turbines are heavily strained by thermal and centrifugal forces during their life span which lead to cracking.

3. 2. Thermo-mechanical fatigue crack propagation in a single-crystal turbine blade

   Master-uppsats, Linköpings universitet/Mekanik och hållfasthetslära

   Författare :Andreas Koernig; Nicke Andersson; [2016]
   Nyckelord :Thermo-mechanical fatigue; crack propagation; single-crystal; turbine blade; FRANC3D;

   Sammanfattning : Simulation of crack growth in the internal cooling system of a blade in a Siemens gas turbine has been studied by inserting and propagating cracks at appropriate locations. The softwares used are ABAQUS and FRANC3D, where the latter supports finite element meshing of a crack and calculation of the stress intensities along the crack front based on the results from an external finite element program.

4. 3. Accounting for non-linear effects in fatigue crack propagation simulations using FRANC3D

   Master-uppsats, Linköpings universitet/Hållfasthetslära; Linköpings universitet/Tekniska högskolan

   Författare :Christian Busse; [2014]
   Nyckelord :;

   Sammanfattning : In this thesis methods to account for non-linear effects in fatigue crack propagation simulations using FRANC3D are evaluated. FRANC3D is a crack growth software that supports automated crack growth in the FE mesh using the power of an external FE code. LÄS MER
