1. 1. Soil-Steel Composite Bridges : Research advances and application

   Författare :Amer Wadi; Raid Karoumi; Lars Pettersson; Ian D. Moore; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flexible culvert; Soil‒steel composite bridge; Sloping terrain; Swedish design method; Finite element model; Ultimate capacity; Avalanche load; Failure load; Low soil cover; Failure mechanism; Long-span; Byggvetenskap; Civil and Architectural Engineering;

   Sammanfattning : Soil-steel composite bridges are considered competitive structures being an economical alternative to similar span concrete bridges. This frequently stimulates practitioners to push their design limits and expand the different areas of application including their performance in sloping terrain. LÄS MER

3. 2. Concrete Bridges : Improved Load Capacity

   Författare :Jonny Nilimaa; Terje Kanstad; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

   Sammanfattning : There are many beautiful old structures around the world, some of which were designed for completely different purposes than their current applications. For example, Swedish railway bridges were only designed to carry axle loads up to 200 kN in the beginning of the 20th century, while modern loads can be twice as high. LÄS MER

4. 3. Failure Prediction of Complex Load Cases in Sheet Metal Forming : Emphasis on Non-Linear Strain Paths, Stretch-Bending and Edge Effects

   Författare :Alexander Barlo; Tobias Larsson; Mats Sigvant; Md. Shafiqul Islam; Johan Pilthammar; Karl Brian Nielsen; Blekinge Tekniska Högskola; []

5. 4. Compressive failure of unidirectional NCF composites

   Författare :Dennis Wilhelmsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aerospace; Fibre misalignment; Compressive failure; NCF composite;

   Sammanfattning : With more people flying every year, new technologies are needed to reduce our impact on the environment. One option is to reduce the energy used in flight by introducing lighter materials such as carbon fibre reinforced polymers (CFRP). LÄS MER

7. 5. Mechanical Load Identification for Spontaneous Tool Failure Monitoring

   Författare :Jinming Zhou; Industriell Produktion; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materiallära; Material technology; Monitoring; Cutting force; Identification; Cutting; Manufacturing; materialteknik;

   Sammanfattning : The problem of spontaneous cutting tool failure, such as tool chipping and breakage, is becoming more and more important in the manufacturing technology. The sponataneous tool failure is usually associated with the stresses subjected on the tool during a metal cutting process. LÄS MER
