A Posteriori Error Estimation for Finite Element Methods and Iterative Linear Solvers
(Dr. ingeniøravhandling, 0809-103X; 2001:98, Doctoral thesis, 2001)This thesis addresses a posteriori error estimation for finite element methods and iterative linear solvers. Adaptive finite element methods have gained a lot of popularity over the last decades due to their ability to ... -
A Probabilistic Approach in Failure Modelling of Aluminium High Pressure Die-Castings
(Doctoral thesis at NTNU;2015:137, Doctoral thesis, 2015)Aluminium high pressure die-castings have become essential elements of a modern car body in recent years. The high pressure die-casting method enables to produce thinwalled components of complex geometries. This advantage ... -
A probabilistic approach to the value chain of underground iron ore mining: From deposit to product
(Doktoravhandlinger ved NTNU, 1503-8181; 2005:65, Doctoral thesis, 2005)Mining activities will eventually deplete any deposit. In a sustainability perspective, the deposit should therefore be utilised optimally during production. A prerequisite to achieve this is the deliberate and consistent ... -
A probabilistic-based methodology for evaluation of timber facade constructions - The Performance to withstand biodeterioration
(Doctoral theses at NTNU;2018:69, Doctoral thesis, 2018)Mould and decay are biodeterioration phenomena that jeopardize the integrity, functionality and durability of timber façade constructions. Accounting for them during the design stage is crucial for the prevention of social ... -
