   Sammanfattning : Compression perpendicular to the grain (CPG) of wood is a typical loading situation in timber structures. It has been an extensively studied research topic for decades, due to the highly ductile behavior of wood under such loading, the large variations in mechanical properties, and the relevance of these properties in structural design.

3. 22. A MATTER OF NUTRIENT EXCESS AND SHEAR STRESS

   Författare :Ramasri Sathanoori; Kardiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : The metabolic syndrome is a clustering of several risk factors associated with diabetes and cardiovascular disease. Diabetes is a global problem with 90% of patients suffering from type 2 diabetes (T2D), which is attributable to various factors including genetic predispositions and lifestyle. LÄS MER

4. 23. Effect of shear cutting on metal fatigue

   Författare :David Gustafsson; Erik Olsson; Jörgen Kajberg; Pär Jonsén; Henrik Sieurin; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Punching; Trimming; Shear cutting; Fatigue; HCF; Residual stresses; Hållfasthetslära; Solid Mechanics;

   Sammanfattning : Lightweighting of automotive and heavy-duty vehicle components is an important task that does not need any further motivation or background. It can be read in a large part of the technical papers in the field. A common approach for finding lighter solutions is to increase the material grade while decreasing the material thickness.

5. 24. Fluid Dynamics and Granular Growth in High Shear Wet Granulation

   Författare :Anders Darelius; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Coalescence kernel; Frictional Stress Models; Laser Doppler Anemometry; Population balances; CFD; EFD; High shear granulation; High speed imaging; Multi-dimensional; Multiphase flows;

   Sammanfattning : High shear wet granulation is a key step in the manufacturing of tablets in the pharmaceutical industry. From the pharmaceutical industry’s point of view, there is a desire for predictive quantitative process models to be able to make in-silico process and scale-up simulations, which would shorten and reduce the cost of technology transfer from laboratory scale to manufacturing scale in drug development.

7. 25. The modified Iosipescu shear test for orthotropic materials

   Författare :Niklas Melin; Jonas Neumeister; Gradin Per; KTH; []
   Nyckelord :composite; modified Iosipescu tet; shear test; strain field uniformity; TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : AbstractThe Iosipescu shear test, also known as asymmetric four point bending of a V-notched beam,is frequently used for measuring in-plane shear properties of composites. The ASTM standard(ASTM D-5379-05) regulates how the test is to be performed. LÄS MER
