  1. 16. CAE modelling of cast aluminium in automotive structures

    University essay from Linköpings universitet/Mekanik och hållfasthetslära

    Author : Subrat Singh; Sreehari Veditherakal Shreedhara; [2019]
    Keywords : Material failure model; LS- Dyna; Non-linear Finite Element analysis; Cast aluminium; Explicit FEA; LS-DYNA; Drop tower; Spring tower; Strut Tower; FEM; CrachFEM; ANSA;

    Abstract : In the automobile industry, there is a big push for the automotive car manufacturers to base engineering decisions on the results of Computer Aided Engineering (CAE) solutions, and to transform the prototyping and testing, from a costly iterative process to a final verification and validation step. The variability in components material properties and environmental conditions together with the lack of knowledge about the underlying physics of complex systems often make it impractical to make reliable predictions based on only deterministic CAE models.

    Abstract : Diesel engines produce large amounts of nitrogen oxides (NOX) while running. Nitrogen oxides are highly toxic and also contribute towards the formation of tropospheric ozone. READ MORE

  4. 18. High Temperature Tribology in Hot Stamping

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Evan Kurnia; [2019]
    Keywords : high temperature tribology; hot stamping; acoustic emission; condition monitoring; hardfacing;

    Abstract : Many automotive components are made of Al-Si coated ultra-high strength boron steel (UHSS) and are produced by hot stamping process. In this process, the workpiece is heated to an austenitizing temperature and is then formed and quenched simultaneously between the tools to achieve the desired shape and high strength. READ MORE

  5. 19. Acousto-Electromagnetic Interaction in Materials for Aerospace Composites

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Niklas Wingren; [2019]
    Keywords : Non-destructive testing; Ultrasound; mm-waves; Photoelasticity; Multiphysics; Technology and Engineering;

    Abstract : Non-destructive testing (NDT) is a vital part of aerospace manufacturing due to high demands for quality and safety. Advances in materials science have given rise to aerospace composites with highly improved properties compared to traditional materials. READ MORE

  6. 20. Improvement Strategies in Construction Sites : Development of Rapid Site Assessment for House-building Industry

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Pontus Urban; [2019]
    Keywords : Rapid Site Assessment; RSA; Lean; Lean Construction; House-building industry;

    Abstract : The construction industry has deteriorated during the past 40 years. Up to 35 % of the production cost is from wastes. The manufacturing industry has had an opposite development, in many cases owing to the contributions of Lean Production and various assessment tools. READ MORE
