1. 1. Efficient FE Modeling of Large Casted Parts

   University essay from KTH/Maskinkonstruktion

   Author : Lalitha Swetha Amirapu; Haswanth Yalamanchili; [2023]
   Keywords : FE modeling; Large casted parts; Meshing techniques; Mid-surface modeling; FE-modellering; Stora gjutna delar; Meshing-tekniker; Mid-Surface modellering;

   Abstract : The design and analysis of large casted parts present significant challenges due to their complex geometry. Finite Element (FE) modeling is a vital tool for understanding the performance of casted components. However, the computational requirements associated with these parts often lead to excessive processing times and resource utilization. READ MORE

3. 2. Linear Impact of Bicycle Helmet – Experimental Testing and FE-modelling

   University essay from KTH/Hållfasthetslära

   Author : Ludvig Dahlin; Ebba Larsson Regnström; [2022]
   Keywords : FEM; Finite element method; bicycle helmet; impact modelling; solid mechanics; FEM; Finita element-metoden; cykelhjälm; islagsmodellering; hållfasthetslära;

   Abstract : The aim with this master thesis was to set up a FE-simulation of an impact test of a bike helmet in LS-DYNA that correlates well with the peak acceleration score of a real life impact test. Furthermore, a parametric study has been performed in LS DYNA to investigate the robustness of the model, as well as to see which parameters have a great influence on the peak acceleration score.

4. 3. Operational modal analysis and finite element modeling of a low-rise timber building

   University essay from Linnéuniversitetet/Institutionen för byggteknik (BY)

   Author : Viktor Petersson; Andreas Svanberg; [2021]
   Keywords : Timber structure; Dynamic behavior; Operational modal analysis; FE-modeling; Mode shape; Natural frequency.; Träbyggnad; Dynamiskt beteende; Operational modal analysis; FE-modellering; Egenmod; Egenfrekvens.;

   Abstract : Timber is a building material that is becoming more common and of interest for use in high-rise buildings. One of the reasons is that timber requires less energy input for the manufacturing process of the material compared to non-wood based materials. READ MORE

5. 4. FE-Modelling of a Joint for Cross-Laminated Timber

   University essay from Karlstads universitet/Avdelningen för maskin- och materialteknik

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

   Abstract : 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. READ MORE

6. 5. Timber Concrete Composite floors with Cross Laminated Timber - Structural behavior & Design

   University essay from Lunds universitet/Avdelningen för Konstruktionsteknik; Lunds universitet/Institutionen för byggvetenskaper

   Author : Albin Forsberg; Filip Farbäck; [2020]
   Keywords : timber concrete composite; TCC; floors; cross-laminated timber; CLT; structural behavior; design methods; Gamma method; Equivalent gamma method; Extended gamma method; RFEM; first natural frequency; serviceability limit state; ultimate limit state; Technology and Engineering;

   Abstract : På grund av den ökade miljö- och klimatmedvetenheten har övergången till förnybara material påskyndats, och detsamma gäller intresset för träbyggande. Med att bygga högt i trä kommer dock ett flertal konstruktionsmässiga utmaningar, där en av utmaningarna är dynamik på grund av träets låga egenvikt jämfört med andra mer konventionella byggnadsmaterial.
