  2. 11. Reliability Evaluation of Distribution Systems Considering Failure Modes and Network Configuration

    Author : Sajeesh Babu; Patrik Hilber; Chanan Singh; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Power distribution networks are recognized as the constituent part of power systems with the highest concentration of failure events. Even though the faults in distribution networks have a local effect when compared to the generation and transmission sides, major contingency escalation events are being more frequently reported from this section.

  4. 12. Transverse failure initiation in polymer composites

    Author : Leif Asp; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymeric Composite Materials; Polymera konstruktionsmaterial;

    Abstract : Transverse failure is one of the most important failure modes in polymer composites. The phenomenon often causes the first deviations from nonlinear laminate behavior. Also, in pressure vessels and pipes, fluid leakage through a path of transverse cracks is often the limiting design criterion. READ MORE

  5. 13. Safety Format for Non-linear Analysis of RC Structures Subjected to Multiple Failure Modes

    Author : Filippo Sangiorgio; Johan Silfwerbrand; Giuseppe Mancini; Diego Allaix; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This thesis treats the safety format for non-linear analysis of reinforced concrete (RC) structures subjected to multiple failure modes. The purpose is to identify questions which are poorly understood and ambiguous about the behaviour of structures that may fail due to a number of possible failure modes (e.g. READ MORE

  6. 14. Explosions in urban environments: Modelling of gas explosions and risk of premature shear failure in reinforced concrete structures

    Author : Fabio José Lozano Mendoza; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; blast strength; urban road environments; computational fluid dynamics; blast loading; Vapour cloud explosions; factorial design; premature shear failure; Monte Carlo method; model uncertainty;

    Abstract : The risk for accidental gas explosions in urban environments has increased in Sweden in recent years. This is due to densification of existing urban centres and the rise of vehicles powered by alternative fuels. READ MORE

  7. 15. Predominant failure mechanisms at the Kiirunavaara mine footwall

    Author : Mikael Svartsjaern; Diego Mars Ivars; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och berganläggningsteknik;

    Abstract : The Luossavaara-Kiirunavaara Aktiebolag (LKAB) Kiirunavaara mine is a large scale sub-level caving (SLC) mine in northern Sweden. The use of SLC as a mining method inherently causes significant rock mass movements above the extraction level. READ MORE
