  1. 1. Static and dynamic characterization of elastomers by a modified hardness test

    University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

    Author : Omar Chouman; [2019]
    Keywords : Rubber; elastomer; modified hardness test; dynamic and static characterization; damping; dynamic shear modulus; hyperelastic material; hyperelastic constants; finite element method; FEM; FEA; Abaqus; Volvo Cars; Technology and Engineering;

    Abstract : Today rubber can be found in many different applications, such as vibration dampers, tyres, clothes and gaskets. Two different types of rubbers are used today, namely the natural rubber and synthetic rubber. Natural rubber is made of a milky substance called latex, which is obtained from special trees found in tropical countries. READ MORE

  3. 2. Paleogeography and shore displacement of Eastern Gotland between 9.5 and 2.8 ka cal BP

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Aleftin Barliaev; [2017]
    Keywords : ;

    Abstract : Located in the middle part of the Baltic, the island of Gotland underwent major environmental changes, associated with different stages of the development of the basin during the Holocene, and therefore represents a promising location for shore-displacement studies. This thesis is focused on a palaeohydrological evolution of the Lina Mire, central eastern part of Gotland, in the Middle Holocene and aims to reconstruct the timing and environment of the Littorina transgression.

  4. 3. Paleoenvironment and shore displacement since 3200 BC in the central part of the  Långhundraleden Trail, SE Uppland

    University essay from Institutionen för naturgeografi och kvartärgeologi (INK)

    Author : Christos Katrantsiotis; [2013]
    Keywords : Shore displacement; isostatic variability; Uppland; saddle-point; paleoenvironment;

    Abstract : In this study, litho-, bio- and chronostratigraphic investigations combined with RTK GPSleveling have been carried out to reconstruct the paleoenvironment in the central part of theLånghundraleden Trail. The area displays four shallow lake basins of varyingmorphologies. The basins are now covered with peat as a result of infilling and overgrowth. READ MORE

  5. 4. Wave attenuation in stands of common reed(Phragmites australis) and its consequences on sediment resuspension

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Per Falås; [2007]
    Keywords : Phragmites australis; Sediment resuspension; Shallow lakes; Alternative stable states; Civil engineering; Stands of common reed; offshore technology; hydraulic engineering; Wave damping; soil mechanics; Väg- och vattenbyggnadsteknik; Technology and Engineering;

    Abstract : Common reed is found in near-shore areas of many European lakes, where it forms dense stands. As waves are influenced by obstacles along the wave path, water and sediment motions caused by waves are affected by these stands. READ MORE
