1. 16. INTERMEDIATE-SCALE TESTS AND CONE CALORIMETER TESTS - FIRE BEHAVIOUR OF SELECTED FACADE MATERIALS

   Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

   Författare :Tanja Cernosa; [2020]
   Nyckelord :Fire behaviour; Intermediate-scale facade tests; cone calorimeter; stone wool; phenolic foam; WRB; Technology and Engineering;

   Sammanfattning : In the last few years, the implementation of well-ventilated façades in buildings increased due to their improved energy performance. However, their double-wall construction due to the limited airflow within an air cavity represents a significant fire risk, since the flames that spread into the air cavity can elongate up to ten times.

3. 17. Adhesive modelling in multi-material structures : Evaluating the strength and fatigue life of adhesive joints

   Master-uppsats, Linköpings universitet/Mekanik och hållfasthetslära

   Författare :Nitin Narayanaswamy; [2020]
   Nyckelord :Adhesive Joints Strength Calculation J Integral Method Energy Release Rate Theory Crack Finite Element Analysis Multi Material Structures Automotive;

   Sammanfattning : Advancements in material science and manufacturing techniques are enabling the use of lightweight metal alloys and polymer composites in several combinations and shapes for producing more efficient and lightweight structures for automotive applications without compromising strength, stiffness and/or durability. When evaluating the strength of the structure, the joints are of importance. LÄS MER

4. 18. Virtual Material Testing of Adhesive Joints

   Master-uppsats, KTH/Hållfasthetslära

   Författare :Vinit Jethalal Nagda; [2020]
   Nyckelord :;

   Sammanfattning : The automotive industry has shown an increasing interest in adhesive bonding for mixed-material joining. Modern design methods are critically dependent on accurate material models and data for numerical methods to enable the simulation of a design prototype early in the design process. LÄS MER

5. 19. Combining luminescence dating and sedimentary analysis to derive the landscape dynamics of the Velická Valley in the High Tatra Mountains, Slovakia

   Master-uppsats, Lunds universitet/Geologiska institutionen

   Författare :Roos van Wees; [2020]
   Nyckelord :IRSL; Chronology; Sedimentology; Landscape development; Middle Pleistocene; Modern Analogues; Clast shape analysis; Maximum particle size; High Tatras; Slovakia; Earth and Environmental Sciences;

   Sammanfattning : Luminescence dating is widely used in combination with sedimentological analysis to reconstruct the landscape development of the Quaternary period. Here, quartz and K-feldspar measurements are used to date and evaluate the luminescence characteristics of sediments from seven sites of the lower part of the Velická valley (995-1250 m a.s.l.

7. 20. Characterization of thin laminate interface by using Double Cantilever Beam and End Notched Flexure tests

   Master-uppsats, Blekinge Tekniska Högskola/Institutionen för maskinteknik

   Författare :Moiz Majeed; Rahitya Venkata Teja Geesala; [2020]
   Nyckelord :Double Cantilever Beam DCB ; End-Notched Flexure ENF ; Fracture toughness; Low density Polyethylene LDPE ; Three-point bending test;

   Sammanfattning : 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.
