  1. 1. Ductile damage modeling of the machining process

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : SENAD RAZANICA; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ductile fracture; Damage threshold criterion; Damage evolution; Machining simulation; Mesh dependence; Thermodynamics; Johnson-Cook; Damage driving energy;

    Abstract : Machining processes are among the most common manufacturing processes for producing components used on a daily basis. It is a complex material removal process. Today, the research and development within the manufacturing industry is addressed by cost efficient numerical simulation strategies rather than by costly experimental procedures. READ MORE

  2. 2. Moisture Conditions in Exterior Wooden Walls and Timber During Production and Use

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Lars Olsson; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; laboratory test; MRD-index; moisture; driving rain; hysteresis; wood; precipitation; timber; weather barrier; mould growth; façade; wall; wind barrier; measurement; field test; mold;

    Abstract : Thermal insulation of building envelopes has improved over the years. This means that building envelope have become more susceptible to defects, with an increased risk of moisture damage. The criteria for energy consumption have become more rigorous, but the shift should not lead to moisture problems. READ MORE

  3. 3. Moisture Safety in Wood Frame Buildings - Blind evaluation of the hygrothermal calculation tool WUFI using field measurements and determination of factors affecting the moisture safety

    University dissertation from Byggnadsfysik LTH, Lunds Tekniska Högskola

    Author : Solof Mundt Petersen; Lunds universitet.; Lund University.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Blind Validation; Moisture Safety; Hygrothermal Calcualtion Tool WUFI; Wood Frame Buildings;

    Abstract : Popular Abstract in Swedish Hårdare krav på lägre energianvändning i byggnader samt ökade energipriser har gjort att välisolerade hus har blivit vanligare. Ökad medvetenhet om koldioxidens påverkan på klimat-förändringarna har också ökat intresset för trähus. READ MORE

  4. 4. On the Modelling of Fracture Using Strong Discontinuities

    University dissertation from Byggnadsfysik LTH, Lunds Tekniska Högskola

    Author : Martin Fagerström; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fracture; strong discontinuity; material forces; finite deformations; FEM;

    Abstract : The major concern of this work is the constitutive and numerical modelling of fracture,based on strong discontinuity formulations. More particularly, an extended finiteelement approach is used, where the total displacement is separated in two mutuallyindependent fields, representing the continuous and discontinuous displacement respectively.

  5. 5. Structural Integrity Analysis of Critical Elements of RoPax Ships

    University dissertation from Byggnadsfysik LTH, Lunds Tekniska Högskola

    Author : Ulf Karlsson; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; safety; IACS UR S8; RoRo; experiments; ship collision; RoPax; finite element analysis; event-chain; bow-door;

    Abstract : The potentially costly consequences of a lost ship in the form of fatalities, property, cargo and related industries, as well as pollution of the environment in the form of oil spill, etc., and the public view are the driving forces for developing safer ships. Especially RoRo-ferries, i.e. READ MORE
