1. Dynamiskt belastade tribologiska system under plastisk formning, del II --- analyserade genom akustisk emission
Sammanfattning : The dynamic friction process and contact surface between tool and working material in a plastic forming process is hard to describe in mathematical form and hard to monitor and control in real time. High production speed and highly optimised forming operations result in great demands on the control equipment. LÄS MER
2. Bonding Ability Distribution of Fibers in Mechanical Pulp Furnishes
Sammanfattning : This thesis presents a method of measuring the distribution of fiber bonding ability in mechanical pulp furnishes. The method is intended for industrial use, where today only average values are used to describe fiber bonding ability, despite the differences in morphology of the fibers entering the mill. LÄS MER
3. Crack location in steel structures using acoustic emission techniques
Sammanfattning : Denna avhandling utvärderar möjligheten att använda akustisk emission (AE) för att detektera och lokalisera sprickor i stora stålkonstruktioner med ett långt avstånd mellan givarna. De industriella/ekonomiska motivet för projektet är att en noggrannare undersökning av befintliga konstruktioners tillstånd medför att utbyte av dessa konstruktioner kan skjutas på framtiden med bibehållen säkerhet, vilket i sin tur medför besparingar för till exempel broägare.

4. High Performance Manufacturing of Advanced Thin Plates ─ Forming of Titanium and Stainless Steel Materials
Sammanfattning : The manufacturing industry represents a highly important sector of the Swedish economy. The increasing demands placed on the quality and performance of products that are manufactured places increasing demands on the manufacturing processes involved. LÄS MER
5. Tyre/road interaction : A holistic approach to the functional requirements of road surfaces regarding noise and rolling resistance
Sammanfattning : Increased fuel consumption, increased greenhouse gas emission, diminishing real-estate prices and increased health issues are some of the negative effects on the climate, on the environment and on the society from tyre/road rolling resistance and noise. The first two aspects are affected by energy dissipation in the tyre/pavement contact and are related to rolling resistance. LÄS MER
