2. 1. Structural Behavior of Reinforced High-Strength Concrete Columns

   Author : Christina Claeson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sustained loading; columns; slenderness; finite element analyses; nonlinear fracture mechanics; high-strength concrete; short-term loading; eccentricity;

   Abstract : The high compressive strength of high-strength concrete is especially advantageous in compressed members such as columns, which can be made more slender and, consequently, make economic benefits possible. However, the behavior of high-strength concrete columns is not yet fully understood. READ MORE

4. 2. Composite Columns of Hollow Steel Sections Filled with High Strength Concrete

   Author : Marianne Grauers; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : In the design of buildings today, great effort is made to increase the structural flexibility. This has resulted in a demand for columns with reduced cross sections. To achieve a high load bearing capacity with a small cross sectional area, it is worthwhile to study the possibility of utilizing high strength concrete and composite effects. READ MORE

5. 3. Wrinkling of sandwich panels for marine applications

   Author : Linus Fagerberg; KTH; []
   Keywords : wrinkling; local buckling; imperfection; stability; anisotropy; sandwich;

   Abstract : The recent development in the marine industry with largerships built in sandwich construction and also the use of moreadvanced materials has enforced improvements of design criteriaregarding wrinkling. The commonly used Hoff’s formula isnot suited for the highly anisotropic fibre reinforced sandwichface sheets of today. READ MORE

6. 4. Surface Integrity of Case-hardened Gears - with Particular Reference to Running-in and Micropitting

   Author : Dinesh Mallipeddi; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; surface chemistry; residual stresses; surface asperities; micropitting; running-in; Gears; plastic deformed regions PDR ; deformation bands;

   Abstract : A gearbox with gears of different sizes is part of a vehicle transmission system and plays an important part in transmitting the engine power to the wheels. The efficient energy transmission highly relies on the performance of gears. Together, the mesh efficiency and durability determines the performance of gears. READ MORE
