1. Non destructive testing methods for integrity determination of concrete structures
Sammanfattning : The ageing of concrete structures can be a threat to human safety as well as being a huge economical factor in the near future. Lifetime prediction and damage assessment of concrete structures will be a growing part of infrastructure planning. LÄS MER
2. Non-destructive measurement of spiral grain with computed tomography
Sammanfattning : Spiral grain is a wood feature that is formed in the living tree. Timbers sawn from trees with severe spiral grain have a great tendency to twist when the moisture content changes. This is a big problem in the wood products manufacturing process. LÄS MER
3. Combined speckle interferometry and speckle correlation for non-destructive testing
Sammanfattning : When a sample is studied during loading in a tensile test machine, the sample is often exposed to rigid body motions during loading at the same time as it deforms due to tension. Therefore, the small deformation field is hard, or impossible, to measure when it is overlaid by a large motion. LÄS MER
4. Non-destructive detection of glue deficiency in laminated wood using thermography
Sammanfattning : The purpose of the work described in this doctorate thesis has been to study the potential of the non-contact and non-destructive test (NDT) method, thermography, to detect glue deficiency beneath a thin laminated layer of wood. The technological applications can for example be found in the parquet flooring industry. LÄS MER
5. Air and Water Tightness in Building Envelopes - Evaluation of Methods for Quality Assurance
Sammanfattning : The purpose of this work is to contribute to a process formaking buildings with good function and to avoid prematurefaults.The design, construction and installation of low-slopedroofs are important parts of creating a durable building. LÄS MER
