   Författare :Joran van Blokland; Stergios Adamopoulos; Anders Olsson; Jan Oscarsson; Mark Hughes; Linnéuniversitetet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; checks; cracks; digital image correlation; four-point static bending; fracture characteristics; grade determining properties; non-destructive testing; Norway spruce; machine learning; outdoor above-ground exposure; timber grading; scanning electron microscopy; scanning of fibre direction; strain distribution; ThermoWood®; weathering; Forestry and Wood Technology; Skog och träteknik; Byggteknik; Civil engineering;

   Sammanfattning : Thermally modified timber (TMT) has gained market share in Europe as an environmentally friendly and durable building material. Unfortunately, TMT products are currently prohibited for use in structural applications as there is insufficient data to estimate the loss in strength due to thermal modification. LÄS MER

3. 2. Moisture Conditions in Exterior Wooden Walls and Timber During Production and Use

   Författare :Lars Olsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; laboratory test; MRD-index; moisture; driving rain; hysteresis; wood; precipitation; timber; weather barrier; mould growth; façade; wall; wind barrier; measurement; field test; mold;

   Sammanfattning : Thermal insulation of building envelopes has improved over the years. This means that building envelope have become more susceptible to defects, with an increased risk of moisture damage. The criteria for energy consumption have become more rigorous, but the shift should not lead to moisture problems. LÄS MER

4. 3. Numerical Modelling of Timber Building Components to Prevent Disproportionate Collapse

   Författare :Johannes A. J. Huber; Sven Berg; Dick Sandberg; Mats Ekevad; Ulf Arne Girhammar; Jan-Willem G. van de Kuilen; Luleå tekniska universitet; []

   Sammanfattning : An increasing number of multi-storey buildings are being constructed with engineered wood products, such as glulam or cross-laminated timber (CLT). Multi-storey timber buildings can be safely designed for foreseeable loads, but knowledge is limited concerning their ability to survive unforeseeable events, e.g. LÄS MER

5. 4. The measurement of compression wood and other wood features and the prediction of their impact on wood products

   Författare :Micael Öhman; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Technology;

   Sammanfattning : Wood is a complex and highly variable biological material formed to give the tree best possible conditions for sustaining life. Thus every piece of wood is possessed of unique qualities. LÄS MER

7. 5. Outsourcing in the Wood Product Manufacturing Sector A Combined Customer and Supplier Perspective

   Författare :Daniel Nordigården; Staffan Brege; Jakob Rehme; Dan Andersson; Lars Bengtsson; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Outsourcing; driving forces; forward integration; supplier value-adding strategies; parallel production; wood products and sawmills; Industrial organisation; administration and economics; Industriell organisation; administration och ekonomi;

   Sammanfattning : Outsourcing can be defined as transferring an activity from internal to external control. This thesis studies outsourcing in the wood product manufacturing (WPM) sector from both a customer and supplier perspective. LÄS MER
