1. Non-Linear FE-Analysis of a Composite Action Girder with Coiled Spring Pins as Shear Connectors
University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserAbstract : For bridges to cope with increased requirements such as increased loads, strengthening work can be carried out. In cases where older steel-concrete bridges do not have a composite action, an alternative is to create composite-action to achieve a higher flexural strength. It is introduced by post-installing shear connectors. READ MORE

2. Evaluation of SCPT-surveys as method for accessing dynamic modulus
University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserAbstract : The purpose of this master thesis is to evaluate the results from the completed SCPT (Seismic Cone Penetration Test) surveys with respect to the methods ability to estimate dynamic young´s modulus. This has been done by comparing the result from SCPT to other seismic methods and dynamic parameters converted from “static” geotechnical surveys. READ MORE

3. Binder Migration in Double Pressed Drill Bit Inserts
University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Fasta tillståndets fysikAbstract : It is possible to produce functionally graded cemented carbides on a large scale by double pressing. Being able to predict the binder migration in WC-Co cemented carbides during the sintering is essential to the design of such cemented carbides. The cobalt content is one of the main factors determining the hardness gradient. READ MORE

5. Tribological testing of top hammer drill buttons
University essay from Uppsala universitet/Tillämpad materialvetenskapAbstract : In the present work further modifications are implemented to an existing test setup for the evaluation of the wear of cemented carbide drill buttons in rock drilling applications. The test setup has been evaluated in previous diploma works, which has shown that the test successfully mimics the wear seen in rock drilling applications. READ MORE
