1. Structural-acoustic vibrations in wooden assemblies : Experimental modal analysis and finite element modelling
Abstract : This doctoral thesis concerns flanking transmission in light weight, wooden multi-storey buildings within the low frequency, primarily 20-120 Hz. The overall aim is to investigate how the finite element method can contribute in the design phase to evaluate different junctions regarding flanking transmission. READ MORE

2. Fractured Rock Masses as Equivalent Continua - A Numerical Study
Abstract : In this thesis, fractured rock masses are treated asequivalent continua for large-scale analyses of rockengineering projects. Systematic developments are made for thedetermination of equivalent mechanical and hydraulic propertiesof fractured rock masses using a hybrid discrete fracturenetwork - distinct element method (DFN-DEM) approach.

3. Investigation of asphalt compaction in vision of improving asphalt pavements
Abstract : Asphalt joints are potentially weakest parts of every pavement. Despite of their importance, reliable tools for measuring their mechanical properties for design and performance assessments are still scarce. READ MORE

4. Simulation-based multi-objective optimization of productivity and worker well-being
Abstract : In industry, simulation software is used to simulate production, making it possible to predict events in production, calculate times and plan production, even in the early phases of the production development process. Software known as digital human modelling (DHM) tools can also be used to simulate humans working in production. READ MORE

5. Numerical prediction of wear in industrial raw material flow
Abstract : Abrasive wear is largely involved in many industrial processes, and has far reaching economic consequences which involve not only the costs of replacement, but also the costs involved in machine downtime and lost production. Constructions and machines like conveyers, chutes and dumper truck bodies are often exposed to abrasive wear during handling of industrial raw granular material flow e. READ MORE
