1. Static and time-dependent mechanical behaviour of preserved archaeological wood : Case studies of the seventeenth century warship Vasa
Abstract : Wooden objects have been widely used in the history of humanity and play an important role in our cultural heritage. The preservation of such objects is of great importance and can be a challenging task. This thesis investigates the static and time-dependent mechanical behaviour of archaeological oak wood from the Vasa warship. READ MORE

2. Effects of Cell Wall Structure on Tensile Properties of Hardwood : Effect of down-regulation of lignin on mechanical performance of transgenic hybrid aspen. Effect of chemical degradation on mechanical performance of archaeological oak from the Vasa ship
Abstract : Wood is a complex material and the mechanical properties are influencedby a number of structural parameters. The objective of this study has been toinvestigate the relationship between the structure and the mechanical propertiesof hardwood. Two levels were of special interest, viz. READ MORE

3. Structure and properties of Vasa oak
Abstract : The Vasa ship is not adequately supported. Measurements of the hull show that the ship deforms and rotate towards the port side. In addition, damages on the hull at support areas have been observed. The damages are due to high compressive loads. READ MORE

4. In-situ assessment of density and material properties in timber structures by non-destructive and semi-destructive testing
Abstract : ABSTRACTIn the assessment of timber structures, diagnostic investigations of the structural members and connections are generally necessary. The assessment often requires appropriate non-destructive testing (NDT) and semi-destructive testing (SDT) techniques. READ MORE

5. The power and the glory : the sculptures of the warship Wasa
Abstract : In 1956 the wreck of the 64-gun Swedish warship Wasa, sunk on her maiden voyage in the harbour of Stockholm the 10th of August 1628, was found at a depth of 32 metres. Preparations for salvaging the ship started, and in April 1961 the Wasa broke the surface after 333 years on the sea bottom. READ MORE
