1. 1. Hybrid bridge deck of timber and corrugated steel plates

   University essay from KTH/Byggnadsmaterial

   Author : Muze Lu; [2023]
   Keywords : ;

   Abstract : Over the years, hybrid structures composed of timber and steel have become a potential alternative to conventional solutions. Recently, corrugated steel plate (CSP) has become more and more popular in structures such as shear walls and roofs due to its favorable mechanical properties. READ MORE

3. 2. Evaluation of a computational method for natural fiber-reinforced plastics

   University essay from KTH/Hållfasthetslära

   Author : Anna Lim; [2023]
   Keywords : PPNF; Composite material; fiber orientation; natural fiber; coupled analysis; PPNF; Kompositmaterial; fiberorientering; naturfiber; kopplad analys;

   Abstract : The importance of using natural fiber composites (NFCs) has been addressed as a substitution for synthetic fibers, such as glass and carbon fibers. This substitution contributes significantly to reducing greenhouse gas emissions, aligning with the environmental responsibilities of engineering industries. READ MORE

4. 3. Incorporating Flax Fiber Composites in Hypercar Panels

   University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

   Author : Hanna Öster; Sara Isorena Guðjónsdóttir; [2023]
   Keywords : sound transmission loss; coincidence frequency; sound pressure level; flax fibre; carbon fibre; ljudtransmission; koincidensfrekvens; ljudtrycksnivå; linfiber; kolfiber;

   Abstract : This thesis investigates sound transmission loss through flat finite panels using composite materials, which incorporate both carbon and flax fibres. The study wascarried out by performing FEM simulations developed and validated in steps. Thevalidation process was time-consuming but crucial in ensuring the model’s reliability. READ MORE

5. 4. A Feasibility Analysis of Natural Composite Alternatives in High Performance Sailing Vessels

   University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

   Author : Sabrina Smith; [2023]
   Keywords : F50 catamaran; sustainable materials; marine applications; flax laminates; mechanical testing; environmental analysis; weight distribution; yacht performance;

   Abstract : The construction of high-performance vessels like the F50 catamaran has traditionally prioritized advanced composite materials and performance-driven design. However, there is a growing need to incorporate sustainable materials and practices, with their performance in marine applications remaining relatively unknown. READ MORE

6. 5. EVALUATION OF MULTI-ZONE MODELLING FOR FIRE RISK ASSESSMENT IN TUNNELS

   University essay from Lunds universitet/Avdelningen för Brandteknik

   Author : Annachiara Nardone; [2023]
   Keywords : tunnels; tunnel fires; multi-zone modelling; Technology and Engineering;

   Abstract : Abstract Tunnels are one of the most complex and delicate elements of the road system. Assessing fire behaviour and fire severity remains the biggest source of uncertainty in risk assessment and is an essential step in the tunnel design process. READ MORE
