1. Fractional Calculus and Linear Viscoelasticity in Structural Dynamics
Sammanfattning : The use of linear viscoelasticity together with fractional calculus in time-domain structural modeling is studied. Both constitutive and structural aspects are investigated. LÄS MER
2. The Finite Element Method for Fractional Order Viscoelasticity and the Stochastic Wave Equation
Sammanfattning : This thesis can be considered as two parts. In the first part a hyperbolic type integro-differential equation with weakly singular kernel is considered, which is a model for dynamic fractional order viscoelasticity. In the second part, the finite element approximation of the linear stochastic wave equation is studied. LÄS MER
3. Thermally Induced Fracture Performance of Asphalt Mixtures
Sammanfattning : A major distress mode in asphalt pavements is low temperature cracking, which results from the contraction and expansion of the asphalt pavement under extreme temperature changes. The potential for low temperature cracking is an interplay between the environment, the road structure and importantly the properties of the asphalt mixture. LÄS MER
4. Respiratory mechanics during mechanical ventilation in health and in disease
Sammanfattning : The elastic pressure-volume (Pel-V) curve of the respiratory system can be used as a guide for improved ventilator management. It may indicate risks of lung damage associated with collapse or overdistension of lung units. LÄS MER
5. Robust Preconditioners Based on the Finite Element Framework
Sammanfattning : Robust preconditioners on block-triangular and block-factorized form for three types of linear systems of two-by-two block form are studied in this thesis. The first type of linear systems, which are dense, arise from a boundary element type of discretization of crack propagation problems. LÄS MER
