Ultimate capacity of aluminium plates under multiple loads, considering HAZ properties
(Dr.ingeniøravhandling, 0809-103X; 2001:56, Doctoral thesis, 2001)The purpose of this work has been to investigate the ultimate capacities of aluminium plates. The aluminium plates are supposed to be part of a marine structure. Their behaviour has been explored by taking advantage of ... -
An Experimental Study of Oil/Water Flow in Horizontal Pipes
(Dr.ingeniøravhandling, 0809-103X; 2001:102, Doctoral thesis, 2001)The purpose of this thesis is to study the behaviour of the simultaneous flow of oil and water in horizontal pipes. In this connection, two test facilities are used. Both facilities have horizontal test sections with inner ... -
Architecture for supply chain analysis and methodology for quantitative measurement of supply chain flexibility
(Doctoral thesis, 2001)One of the biggest challenges for manufacturing supply chains in current business environment is to continuously improve their performance so that their competitiveness can be sustained in long term. Facing this challenge, ... -
Homogenization and computational methods for calculating effective properties of some cellular solids and composite str uctures
(Dr. ingeniøravhandling, 0809-103X; 2001:19, Doctoral thesis, 2001)In this thesis we discuss, develop and apply homogenization and numerical methods for determining effective thermal and stiffness properties of some cellular solids and composite structures. In particular we study and ... -
Full- and Model Scale Study of Wind Effects on a medium-rise Building in a built up Area
(Dr. ingeniøravhandling, 0809-103X; 2002:95, Doctoral thesis, 2002)The present study deals with full- and model scale study of wind effects on a medium-rise building in a built up area. Most low-rise building experiments have been based on an isolated building placed in a relatively ... -
A Study of some Factors in Mechanistic Railway Track Design
(Dr. ingeniøravhandling, 0809-103X; 2002:54, Doctoral thesis, 2002)This thesis is composed of three main parts: The first part that uses classic track models as a basis for further developments, the second part that deals with constitutive behaviour of granular materials and the third ... -
Wind flow studies for drifting snow on roads /
(Dr. ingeniøravhandling, 0809-103X; 2002:82, Doctoral thesis, 2002)During strong winds, drifting snow causes problems on roads in many harsh winter climate countries. Increased snow-removal costs, reduced access and safety problems are typical results of excessive snowdrift sedimentation ... -
