  4. 2. Grain Size and Solid Solution Strengthening in Metals

    Author : Dilip Chandrasekaran; KTH; []
    Keywords : strengthening mechanisms; flow stress; solid solution strengthening; grain size strengthening; micromechanical modelling; AFM; EBSD;

    Abstract : The understanding of the strengthening mechanisms is crucialboth in the development of new materials with improvedmechanical properties and in the development of better materialmodels in the simulation of industrial processes. The aim ofthis work has been to study different strengthening mechanismsfrom a fundamental point of view that enables the developmentof a general model for the flow stress. READ MORE

  5. 3. FRP shear strengthening of reinforced concrete beams

    Author : Gabriel Sas; Giorgio Monti; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fiber reinforced polymers; shear; reinforced concrete; strengthening; model; comparison; literature review; Structural Engineering; Konstruktionsteknik;

    Abstract : The shear failure mechanisms of flexural reinforced concrete (RC) members is highly complex; its precise details cannot be explained with simple analytical relationships, and are the topic of considerable scientific debate. The studies described and examined the three most used shear theories in the world – the fixed angle truss model (45°TM), the variable angle truss model (VAT), and modified compression field theory (MCFT).

  6. 4. Strengthening the Environmental Sustainability of Production Systems through Digitalization

    Author : Xiaoxia Chen; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; digital technology; Industry 4.0; digitalization; manufacturing; mechanisms; environmental sustainability; production system; environmental benefits;

    Abstract : Industrial companies are facing incremental pressure to strive for environmentally sustainable development. This can be attributed to their increased contribution to energy consumption and carbon emissions and the growing international attention focused on global warming. READ MORE

  7. 5. Deformation mechanisms and load distribution in multi-phase engineering materials

    Author : Nitesh Raj Jaladurgam; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Deformation mechanisms; Electron microscopy; Eutectic high entropy alloys; Load distribution; Superalloys; In-situ neutron diffraction;

    Abstract : While the transition to carbon neutral technologies is still in progress, it is vital to reduce the environmental impact of existing processes. The efficiency of combustion processes for e.g. power generation and aviation can be greatly improved by increasing the operating temperature. READ MORE
