1. Constitutive Modelling and Finite Element Analysis of Concrete Structures with Regard to Environmental Influence
Sammanfattning : A constitutive model for concrete is formulated. Tensile fracture is described using a smeared crack approach where the fracrure energy is considered and the shear stiffneess in the cracked region is gradually reduced as crackling develops. LÄS MER
2. Finite Element Analysis of Structures with Nonlinear Material Behaviour
Sammanfattning : .... LÄS MER
3. Wood fibre deformation in combined shear and compression
Sammanfattning : Mechanical pulping for producing pulps from softwood suitable for printing grade papers, like news, is a highly energy-intensive process consuming around 2000 kWh/t in electrical energy. Due to increasing energy costs and environmental issues there is a high demand for decreasing this energy consumption. LÄS MER
4. Thermal stresses in load-bearing glass-timber components
Sammanfattning : Thermal stresses can arise in glass used in architectonic realisations in buildings as a result of solar irradiation: that is, sunlight. The magnitude of these thermal stresses depends on the temperature conditions in the glass in terms of the temperature differences between warm and cold areas. LÄS MER
5. A Finite Element Study of the Shape Stability of Sawn Timber Subjected to Moisture Variations
Sammanfattning : Shape instability in timber products exposed to moisture variation is a serious problem since it can make wood products unsuitable for construction purposes. In this thesis the finite element method has been used to simulate deformations during the drying process.….…. LÄS MER
