  1. 1. Shear Fracture and Delamination in Packaging Materials A study of Experimental Methods and Simulation Techniques

    Detta är en avhandling från Karlskrona : Blekinge Tekniska Högskola

    Författare :Md. Shafiqul Islam; [2016]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Package opening; Shear test specimen; Stress intensity factor; Finite Element simulation; Scanning electron microscopy; Polymers; Interlaminar shear delamination;

    Sammanfattning : Packages are the means of preservation, distribution and convenience of use for food, medicine and other consumer products. Package opening is becoming complicated in many cases because of cutting cost in design and production of opening techniques. LÄS MER

  2. 2. Laser welding and cladding the effects of defects on fatigue behaviour

    Detta är en avhandling från Luleå tekniska universitet

    Författare :Md. Minhaj Alam; Luleå tekniska universitet.; [2012]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Manufacturing Systems Engineering; Produktionsutveckling;

    Sammanfattning : The thesis focuses on weld defects in laser processed materials (for laser welding, laser hybrid arc welding and laser cladding) and their effect on the fatigue life of components. Component properties were studied with particular emphasis on the macro and micro surface geometry, weld defects and clad defects. LÄS MER

  3. 3. A study of the fatigue behaviour of laser and hybrid laser welds

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Md. Minhaj Alam; Luleå tekniska universitet.; [2009]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Manufacturing Systems Engineering; Produktionsutveckling;

    Sammanfattning : This licentiate thesis focuses on the fatigue cracking behaviour of laser and hybrid laser-MAG welded structures. Beside the welding process and the resulting weld, several topics related to fatigue of welded structures are treated such as; macro and micro surface geometry, weld defects and their influence on fatigue performance of welded structures, fatigue analysis by the nominal and effective notch stress method, fatigue life prediction using LEFM (Linear Elastic Fracture Mechanics), fatigue testing, metallurgical analysis, elastic and elastic-plastic finite element analysis.

  4. 4. TOWARDS ACCELERATED SIMULATIONS FOR FLUID FLOW AND HEAT TRANSFER OF LARGE INDUSTRIAL PROCESSES

    Detta är en avhandling från Västerås : Mälardalen University

    Författare :Md Lokman Hosain; Mälardalens högskola.; [2016]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy- and Environmental Engineering; energi- och miljöteknik;

    Sammanfattning : The manufacturing sector is one of the biggest energy consumers. The iron and steel markets in China are growing very fast. Several studies have been performed to evaluate the Chinese steel sector in terms of energy savings and CO2 emissions. LÄS MER

  5. 5. Visualization and mesoscopic simulation in systems biology

    Detta är en avhandling från Stuttgart : OPUS University of Stuttgart

    Författare :Martin Falk; [2013]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Scientific Visualization; GPGPU; Simulation; Systems Biology; Model Development; Signal Transduction;

    Sammanfattning : Biological cells appear everywhere on earth. They might live on their own as unicellular organism, like bacteria, or might form complex organisms consisting of several thousands or millions of cells. Despite their small size of only a few micrometers, they are complex little miracles. LÄS MER
