  1. 1. Automatic Quality Monitoring in GMA Welding using Signal Processing Methods

    University dissertation from Department of Production and Materials Engineering, LTH, Lund University

    Author : Stefan Adolfsson; Lunds universitet.; Lund University.; [1998]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material technology; F; Signal Processing; Automatic Quality Monitoring; GMA welding; Materiallära; materialteknik;

    Abstract : An ongoing continuous process of automatization of the production lines is used in industry to reduce production costs. Automatization of quality control should be seen as part of a cost reduction process, as well as of quality control of the welding. READ MORE

  2. 2. Modelling of Granular Materials

    University dissertation from Department of Production and Materials Engineering, LTH, Lund University

    Author : Aylin Ahadi; Lunds universitet.; Lund University.; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydraulic engineering; Civil engineering; materialteknik; Materiallära; Material technology; binary mixture model; simulations; material modelling; finite element; granular materials; offshore technology; soil mechanics; Väg- och vattenbyggnadsteknik;

    Abstract : The aim of this doctoral study is to develop and implement a material model for granular materials. The course of this work was concentrated upon a non-associated plasticity model with yield surface and the flow potential expressed in terms of the mean stress p and the third stress invariants I3.
