Crack propagation and arrest of structural steels and pipelines
(Doktoravhandlinger ved NTNU, 1503-8181; 2008:105, Doctoral thesis, 2008)Crack arrest of fast running cracks is an important issue for the safety of steel structures. Crack arrest design can prevent fatal damage of large structures by restricting the influence of the incidents. Therefore crack ... -
Crack propagation in a brittle DCB specimen assessed by means of the Williams? power expansion
(Journal article; Peer reviewed, 2019)A double cantilever beam geometry has been chosen in order to investigate the importance of the higher-order terms of the Williams’ power expansion for the crack path estimation. The crack propagation has been tested ... -
Crack propagation in aluminium alloy plates: experiments, modelling and simulation
(Master thesis, 2021)Denne masteroppgaven har studert sprekkpropagering i 1.5mm tykke plater av aluminiumslegeringen AA6016 utsatt for kvasisstatisk- og dynamisk last. Forsøkene har blitt modellert ved bruk av en FEA og en Gurson-Tvergaard-needleman ... -
Crack Risk Assessment in Massive Structures
(Master thesis, 2017)This Master s thesis is the extended version of the project assignment done for TKT4530- Concrete Technology, Specialization Project, and has mainly two parts. The first part studies the effect of the seasons on crack index ... -
Crack risk evaluation of submerged concrete tunnel during hardening phase
(Journal article; Peer reviewed, 2018)Cracking of concrete structures during the hardening phase often seriously compromises not only structure integrity but also durability and long-term service life. Especially for large massive structures, for example, ... -
Cracked components under anti-plane loading: Recent outcomes and future developments
(Journal article; Peer reviewed, 2017)The existence of three-dimensional effects at cracks has been known for many years, but understanding has been limited, and for some situations still is. Understanding improved when the existence of corner point singularities ... -
Cracking Behaviors of Rock-Like Specimens Containing Two Sets of Preexisting Cross Flaws under Uniaxial Compression
(Journal article; Peer reviewed, 2019)Cross flaws occur widely in rock masses and play a crucial role in the failure of rock engineering. This article first experimentally studies the cracking behaviors of rock-like specimens containing two sets of preexisting ... -
Cracking in concrete-debonding length at the concrete/steel interface
(Master thesis, 2016)Investigation of the debonding length at the concrete/steel interface have been investigated based on different types of cracks in concrete. Different methods for investigation have been used in the laboratory. -
Cracking risk of concrete structures in the hardening phase: Experiments, material modeling and finite element analysis
(Doktoravhandlinger ved NTNU, 1503-8181; 2008:198, Doctoral thesis, 2008) -
The cracking risk of hardening concrete exposed to realistic curing temperature regimes and restraint conditions – Experimental investigations of important parameters
(Peer reviewed; Journal article, 2022)Early age cracking in hardening concrete can be evaluated using dedicated calculation methods. Such calculations require a wide selection of input parameters, e.g. autogenous- and thermal deformation, hydration heat ... -
Crane load position control using Lyapunov-based pendulum damping and nonlinear MPC position control
(Chapter, 2019)A crane control system is presented where the crane load can track a position trajectory with ultimately bounded pendulum motions of the load. This is done with an inner loop using a Lyapunov-based damping controller which ... -
Crane Maintenance in the Era of Industry 4.0
(Master thesis, 2017)Today s companies are facing a series of challenges, experiencing difficulty in increasingly specialized and competitive markets and demanding restructuring processes. The industry needs countermeasures to prove their place ... -
Crane Payload Stabilization using Lagrangian Kinematics and Euler Angles
(Master thesis, 2019)Denne oppgaven har som formål å teste en kontrollers evne til å stabilisere en nyttlast samtidig som kranen skal bevege seg i en forhåndsinnstilt bane for en rekke ulike situasjoner. Den presenterer bevegelsesligningene ... -
Crane Pose Estimation using IMU and Computer Vision
(Master thesis, 2022)Kranoperasjoner om bord på skip blir gjennomført til stadighet i maritim industri i dag. Slike kranoperasjoner er utsatt for lastsvingninger på grunn av skipets bevegelser. Lastsvingninger utgjør en risiko for både mennesker ... -
Crane Rig: An Experimental Setup for Developing and Verifying New Control Methods for Marine Crane Operations
(Chapter; Peer reviewed, 2017)This paper will present the derivation of dynamic equations describing the motion of a knuckleboom crane for marine vessels. The dynamics will be derived using Lagrange’s equation, the theory of virtual work and generalized ... -
Crash behavior of obliquely loaded aluminum extrusions
(Chapter, 2002)The energy absorbing capability of obliquely loaded aluminum extrusions was studied through quasi-static experiments. Square aluminum columns in alloy AA6060 were clamped at one end and oblique load conditions were realized ... -
