    Abstract : The aim of this thesis is to interconnect human tactile perception with various physical properties of materials. Tactile perception necessitates contact and relative motion between the skin and the surfaces of interest. READ MORE

  3. 3. Dendritic morphology and ultimate tensile strength of pearlitic lamellar graphite iron

    University dissertation from Jönköping : Jönköping University, School of Engineering

    Author : Vasilios Fourlakidis; Högskolan i Jönköping.; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lamellar graphite iron; Primary austenite dendrite; Ultimate tensile strength; Microstructure model;

    Abstract : The continued development, of cylinder blocks and cylinder heads for heavy truck engines that are made of lamellar graphite iron (LGI) is focused on achieving high ultimate tensile strength (UTS) whilst conforming to environmental regulations. The purpose of this work is to further improve the tensile strength as well as the predictive engineering tools for optimization of LGI aimed to enhance the efforts for producing lighter and sustainable components without sacrificing performance.
