1. Viscoelastic Materials : Identification and Experiment Design
Sammanfattning : Viscoelastic materials can today be found in a wide range of practical applications. In order to make efficient use of these materials in construction, it is of importance to know how they behave when subjected to dynamic load. LÄS MER
2. Transmission of waves through elastic and viscoelastic junctions
Sammanfattning : Transmission of extensional waves through elastic and viscoelastic junctions between elastic and collinear bars have been studied theoretically and experimentally. The models used can be interpreted also for other types of waves (e.g. dilatational waves, shear waves, electromagnetic waves) and systems. LÄS MER
3. Estimation of state and identification of complex modulus based on measurements om a bar traversed by waves
Sammanfattning : Estimation of state and identification of complex modulus based on measurements on non-uniform rods and beams have been studied theoretically and experimentally. Two principal cases were studied. In the first case, the material properties are fully known and the state at a section is to be estimated. LÄS MER
4. A Lagrangian-Eulerian simulation method for viscoelastic flows applied to adhesive joining
Sammanfattning : Viscoelastic flows are important for many industrial processes, such as adhesive joining, polymer extrusion and additive manufacturing. Numerical simulations enable virtual evaluation and product realization, which can support the design phase and reduce the amount of costly physical testing. However, such applications are challenging to simulate. LÄS MER
5. Evaluation of a Measuring System for Determining Extensional Properties
Sammanfattning : Effective and reliable characterisations of fluids are important to gain knowledge of thebehaviour and to govern the properties of a fluid. Since food products often are non-Newtonian, viscoelastic liquids, the characterisation becomes more complicated. LÄS MER
