1. 21. Reinforced Concrete Structures Subjected to Imposed Deformations: A Study of Cracking due to Shrinkage in Slab Foundations for Residential Houses

   University essay from Lunds universitet/Avdelningen för Konstruktionsteknik; Lunds universitet/Institutionen för bygg- och miljöteknologi

   Author : Henrik Johansson; Martin Heinegård; [2020]
   Keywords : Reinforced concrete structures; nonlinear finite element analysis; crack widths; imposed deformations; shrinkage; foundation slabs; fracture mechanics; Atena 2D; Technology and Engineering;

   Abstract : The need for limiting crack widths in reinforced concrete structures is due to durability, tightness towards gaseous and liquid substances, and for aesthetic reasons. Although concrete cracks at relatively low tensile stresses and can not be avoided, strategies for crack control can be adopted to meet the requirements. READ MORE

3. 22. Coarse-Graining Fields in Particle-Based Soil Models

   University essay from Umeå universitet/Institutionen för fysik

   Author : Björn Ahlman; [2020]
   Keywords : Soil mechanics; Soil compaction; Continuum mechanics; Discrete Element Method; Coarse graining; Computational physics;

   Abstract : In soil, where trees and crops grow, heavy vehicles shear and compact the soil, leading to reduced plant growth and diminished nutrient recycling. Computer simulations offer the possibility to improve the understanding of these undesired phenomena. READ MORE

4. 23. Analysis of Paperboard Performance using Digital Image Correlation

   University essay from KTH/Hållfasthetslära

   Author : Yiming Liang; [2020]
   Keywords : Paperboard; Digital image correlation; Comparable stages; Compensation; Kartong; Digital bildkorrelation; Jämförbara tillstånd; Kompensation;

   Abstract : The performance of paperboard materials in packaging application has been investigated and evaluated for a long time. This is because it plays a decisive role for product protection and decoration in packaging applications. Potential damages during transportation sometimes affect the consistency of the performance.

5. 24. Experimental Testing and MaterialModeling of Anisotropy in InjectionMoulded Polymer Materials

   University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

   Author : Sharlin Shahid; Widaad Gukhool; [2020]
   Keywords : Anisotropy; Barlat2004; DIC; Hill48; Polyethylene; Tensile test;

   Abstract : 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

6. 25. Multifunctional Wood Polymer Composites Reinforced with Graphene Nanoplatelets : Investigating if multifunctionality can be achieved in wood polymer composites through the addition of graphene nanoplatelets

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Vanessa Meulenberg; [2019]
   Keywords : Wood polymer composites; graphene; multifunctional; wood flour;

   Abstract : Graphene nanoplatelets (GNPs) were used to reinforce wood polymer composites (WPCs) in order to achieve multifunctionality. Multifunctionality could be achieved through the GNPs because of their excellent mechanical and electrical properties. The research consists of two parts: HDPE/GNP/WF composites and LLDPE/GNP composites. READ MORE
