6. Effect of strain rate on continuum and pre-cracked polymer failure
University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknikAbstract : The main intention of this thesis work was to investigate the effect of strain rate on continuum and pre-cracked polymer failure. Low-Density Polyethylene (LDPE) was chosen to study experimentally and numerically. In order to cover wide range of strain rates, four specific strain rates were selected for the uniaxial tensile tests. READ MORE

7. Accelerated aging of cellulose-based composites in different climate environments : A project provided by Biofiber Tech Sweden AB
University essay from Uppsala universitet/Institutionen för kemi - ÅngströmAbstract : This paper reviews the effects of accelerated aging with increased humidity and temperature on cellulose-based composites. The composites consist of a matrix of plastic reinforced with cellulose fibers. The company Biofiber Tech Sweden AB provided four different composites and a conventional polyolefin as reference.

8. Conceptual design and construction of a UAV wing structure
University essay from KTH/Skolan för teknikvetenskap (SCI)Abstract : This report presents the design of the wing structure for a UAV called Skywalker X8. A model of the UAV was given and analyzed to design a wing box structure that is twice the size of the current model, with "greener" technology and lightweight materials. READ MORE

9. Characterization of thin laminate interface by using Double Cantilever Beam and End Notched Flexure tests
University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknikAbstract : This thesis is intended to identify the mode I and mode II fracture toughness to characterize the thin laminate interface by using the Double Cantilever Beam test (DCB) and End Notched Flexure test (ENF). This study’s thin laminate was Polyethylene Terephthalate and Low-Density Polyethylene (PET-LDPE), which is mostly used by packaging industries in the manufacturing of packages to store liquid food.

10. Experimental Testing and MaterialModeling of Anisotropy in InjectionMoulded Polymer Materials
University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknikAbstract : Experimental characterization of the mechanical properties in a thin injection moulded Low-Density Polyethylene (LDPE) plate is per- formed in this work. Anisotropy in LDPE at different material orientations is measured from the Digital Image Correlation (DIC) observation of the specimens during uniaxial tensile test. READ MORE
