1. 11. Vibration Frequencies as Status Indicators for Tensegrity Structures

   Författare :Nasseradeen Ashwear; Anders Eriksson; Karl-Gunnar Olsson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tensegrity; Pre-stress; Vibration; Health monitoring; Buckling; Temperature effect; Vibration health monitoring VHM; Tensegritet; Förspänning; Vibration; Hälsokontroll; Knäckning; Temperatureffekt; Vibrationsbaserad hälsokontroll; Engineering Mechanics; Teknisk mekanik;

   Sammanfattning :  Applications of vibration structural health monitoring (VHM) techniques are increasing rapidly. This is because of the advances in sensors and instrumentation during the last decades. VHM uses the vibration properties to evaluate many civil structures during the design steps, building steps and service life. LÄS MER

3. 12. Basic Testing and Strength Design of Corrugated Board and Containers

   Författare :Tomas Nordstrand; Byggnadsmekanik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material technology; Materiallära; materialteknik; Produktteknik allmän ; Technology of other products; corrugation; compression; collapse; buckling; bending; box;

   Sammanfattning : Packaging serves a lot of purposes, and would be hard to do without. Packaging protects the goods during transport, saves costs, informs about the product, and extends its durability. A transport package is required to be strong and lightweight in order to be cost effective. LÄS MER

4. 13. Foam Core Materials for High Performance Sandwich Constructions: Preparation, Testing and Properties

   Författare :Mikael Danielsson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; IPN; core material; low temperature; polyurea; polyethersulfone; gradient structure; foam; PVC; sandwich; waste; fire; smoke; toxicity; mechanical properties; Inter Penetrating Polymer Network; dynamic properties; high temperature;

   Sammanfattning : The basic task for foams used as core materials in sandwich constructions is to separate the skin layers in order to enhance stiffness with little contribution to the total weight. However, modern design in sandwich technology require that core materials contribute to the perfor-mance with specific mechanical and physical properties. LÄS MER

5. 14. Characterization of factors interacting in CGI machining : machinability - material microstructure - material physical properties

   Författare :Anders Berglund; Cornel Mihai Nicolescu; Tero Stjernstoft; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CGI; Compacted Graphite Iron; milling; cast iron; machinability; material microstructure; material physical properties; CGI; kompaktgrafitjärn; fräsning; gjutjärn; skärbarhet; mikrostruktur; materialegenskaper; Manufacturing engineering; Produktionsteknik;

   Sammanfattning : The Swedish truck industry is forced to find new material solutions to achieve lighter engines with increased strength. Customers and new environmental regulations demand both higher specific power and more environmentally friendly trucks, and this places a rising pressure on the manufactures. LÄS MER

7. 15. Compression analysis as a tool for technical characterization and classification of pharmaceutical powders

   Författare :Josefina Nordström; Göran Alderborn; Maria Strömme; Katharina Picker-Freyer; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; compaction; compression; granules; Kawakita; mechanical properties; particles; PAT; pharmaceutical powders; tablets; Pharmaceutics; Galenisk farmaci;

   Sammanfattning : There are today strong incentives for an increased understanding of material properties and manufacturing processes to facilitate the development of new technologies in the pharmaceutical industry. The purpose of this thesis was to suggest methods requiring a low sample amount for characterization of technical properties of powders. LÄS MER
