1. 1. FE-Modelling of a Joint for Cross-Laminated Timber

   Master-uppsats, Karlstads universitet/Avdelningen för maskin- och materialteknik

   Författare :Linus Ekhagen; [2021]
   Nyckelord :cross-laminated timber; fe-modelling; continuum damage mechanics; fracture; korslimmat trä; fe modellering; skademekanik; brott;

   Sammanfattning : Woodbe Engineering AB is a freshly started company that has developed a new type of joint for cross-laminated timber (CLT). The joint does not include any metallic fasteners, which improves sustainability, the ergonomics for the workers and time efficiency. LÄS MER

3. 2. Continuous Time Fatigue Modelling for Non-proportional Loading

   Master-uppsats, Linköpings universitet/Mekanik och hållfasthetslära

   Författare :Sajjan Gundmi Satish; [2019]
   Nyckelord :Multiaxial Fatigue Loading; Fatigue Analysis; Continuous Time fatigue model; Endurance Surface; Rainflow Counting; Cyclic loading; Cycle Counting; Damage Evolution; High-cycle fatigue; Non-proportional loading;

   Sammanfattning : Fatigue analysis is a critical stage in the design of any structural component. Typically fatigue is analysed during post-processing, but as the size of the analysed component increases, the amount of data stored for the analysis increases simultaneously. LÄS MER

4. 3. Numerical simulations of Carbon Fiber ReinforcedPolymers under dynamic loading

   Master-uppsats, KTH/Lättkonstruktioner

   Författare :Edoardo Taddei; [2017]
   Nyckelord :;

   Sammanfattning : The ability to withstand dynamic loading represents an important design criteria for crucial applications such as those adopted in the automotive and aerospace industries. Numerical simulations can lead to a reduction of time and costs for designing composite structures by replacing testing campaigns that are performed in order to assess whether the design requirements of the structure are met.

5. 4. Convergence properties of a continuum damage mechanics model for fatigue of adhesive joints

   Magister-uppsats, Högskolan i Skövde/Institutionen för ingenjörsvetenskap

   Författare :Axel Josefsson; Johan Wedin; [2014]
   Nyckelord :Adhesive joints; Cohesive elements; Convergence; Crack growth rate; Damage Mechanics; DCB; Element Size; Fatigue;

   Sammanfattning : The effect of the element length is examined in modelling crack growth in fatigue loading of an adhesive joint. This is done for a cohesive element using an expression for the damage evolution developed at the University of Skövde which is implemented using the UMAT subroutine in the FE-solver Abaqus. LÄS MER
