  1. 6. Size effect in wood : Characterization of mechanical properties using digital image correlation method

    University essay from Uppsala universitet/Tillämpad mekanik

    Author : Amir Saeidi; Olafur Johannsson; [2023]
    Keywords : compression test longitudinal direction; digital image corre- lation DIC ; ncorr; phyton; pinewood; size effect; stiffness matrix; wood- construction; YAWCAM; young’s modulus; digital image correlation DIC ; elasticitetsmodul; furu; kom- pressionstest längs fiberriktning; ncorr; phyton; storlekseffekt; styvhetsma- tris; trä-konstruktion; YAWCAM;

    Abstract : As a natural composite material, wood exhibits complex structural char-acteristics and diverse behavior under compression and tensile forces. Itsanisotropic nature results in mechanical properties that vary depending onthe load direction along its longitudinal, tangential, and radial grains. READ MORE

  3. 7. Parameter study for an energy efficient suspension for a rail vehicle prototype

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Ludvig Danström; [2023]
    Keywords : Delsbo electric; Energy efficiency; Rail vehicle; Suspension system; Delsbo electric; energieffektivitet; fjärder- och dämparsystem; spårfordon;

    Abstract : The push for sustainability in all parts of our society has never been as big as it is currently. One project that aims to produce sustainable innovation in the railway industry is the Delsbo Electric competition where some of the world’s most energy efficient vehicles compete. READ MORE

  4. 8. 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. 9. Microwave curing of composite material

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

    Author : Arief Budi Sanjaya; [2023]
    Keywords : microwave curing; cured sample; uncured sample; numerical model; contact heating.; mikrovågshärdning; härdat prov; ohärdat prov; numerisk modell; kontaktuppvärmning.;

    Abstract : Microwave curing has become a trend in composite processing due to its efficiency in energy consumption compared to the traditional curing method. However, as commonly found in every composite processing, controlling the microwave curing process remains challenging. The most feasible control method is to build a numerical model. READ MORE

  6. 10. 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
