1. Viscoelasticity of transparent wood-polymer biocomposites : Measuring the time-dependence of a delignified birch and poly(methyl methacrylate) composite’s mechanical properties, using digital image correlation
Kandidat-uppsats, KTH/MaterialvetenskapSammanfattning : The viscoelastic behavior of a delignified birch and poly(methyl methacrylate) (PMMA) composite was investigated, in an effort to learn more about the mechanical properties of transparent wood-polymer biocomposites. Tensile creep tests with constant load were performed for native wood, non-delignified, and delignified wood-polymer composites. LÄS MER
2. Methodology for evaluation of long-term mechanical properties of viscoelastic materials
Master-uppsats,Sammanfattning : Additive manufacturing (AM) enables the fabrication of complex geometries using layer-by-layerdeposition of materials like polymers and metals. However, predicting the long-term viscoelasticcharacteristics of AM polymer parts is challenging due to limited available data. LÄS MER
3. Exploration of bioactive additives for hyaluronan based hydrogels : A literature study
Kandidat-uppsats,Sammanfattning : Hyaluronan (HA) is a substance that is commonly used in biomedical applications in the form of hydrogels. One of these biomedical applications is dermatological fillers where HA is cross-linked with 1,4-Butanediol diglycidyl ether (BDDE) to reduce its rapid turnover within tissue. The filler gives a volumetric effect that can fill out wrinkles. LÄS MER
4. Micro-architectured materials for noise and vibration control in high voltage products – design and modelling
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad mekanikSammanfattning : Many Hitachi ABB Power Grids (HAPG) products vibrate and emit noise, but legal limitations of these parameters fuel the development of energy absorption methods used on products. Methods such as Constrained Layer Damping (CLD). LÄS MER
5. Material Characterization for the Simulation of Drop Tests Against PMMA Sheets
Master-uppsats, Jönköping University/JTH, Material och tillverkningSammanfattning : There is a high demand for implementing simulations in the design and product devel-opment processes, avoiding the execution of costly tests on prototypes and giving thechance of discarding unsuitable designs, as well as exploring possible ones without much cost added.This project assignment is to find a suitable way to simulate drop tests on two typesof PMMA sheets, a material widely used on luminaire covers.
