  1. 16. Crystal Plasticity Finite Element Modelling of Tin Crystals Using Phase Fields

    University essay from Lunds universitet/Hållfasthetslära

    Author : Viktor Hultgren; [2018]
    Keywords : crystal plasticity; finite deformation; phase field; MOOSE; FEM; Technology and Engineering;

    Abstract : Tin whiskers have long caused issues to electronic components and made the subject of many articles. According to NASA the oldest reports concerning whiskers date back to the 1940's. The whiskers are single-crystals growing from, for example electronic components. READ MORE

  3. 17. Evaluating spatial mapping using interpolation techniques

    University essay from Linköpings universitet/Institutionen för datavetenskap

    Author : Allan Gholmi; [2017]
    Keywords : ;

    Abstract : In this thesis, the inverse distance weighting, different kriging methods, ordinary least squares and two variants of the geographically weighted regression was used to evaluate the spatial mapping abilities on an observed dataset and a simulated dataset. The two datasets contain the same bioclimatic variable, near-surface air temperature, uniformly distributed over the whole world. READ MORE

  4. 18. Theoretical experiment of GISSMO failure model for Advanced High Strength Steel

    University essay from Högskolan Väst/Avdelningen för produktionssystem (PS)

    Author : Yueyue Wang; [2017]
    Keywords : Failure model; Theoretical experiment; AHSS; Triaxiality;

    Abstract : When developing an electric vehicle, it is essential to evaluate the deformation in and around the battery box for different crash scenarios, and it is necessary to develop a more advanced model that would take into account all the stress modes. Thanks to the excellent properties of Advanced High Strength Steel (AHSS) combine with high strength for more safety and weight reduction for less exhaust emission, AHSS is more and more commonly used in automobile industry.

  5. 19. Optimization of Magnetic Resonance Diffusion Tensor Imaging for Visualization and Quantification of Periprostatic Nerve Fibers

    University essay from KTH/Skolan för teknik och hälsa (STH)

    Author : Mats Nordbrøden; [2015]
    Keywords : Diffusion tensor imaging; Diffusion-weighted imaging; Magnetic resonance imaging; Nerve-sparing prostatectomy; Prostate cancer; Quantitative analysis; Tractography;

    Abstract : Prostatectomy, surgical resection of the whole prostate is a common treatment for high- risk prostate cancer. Common side effects include long-time urinary and or erectile dysfunction due to damage inflicted to periprostatic nerves. READ MORE

  6. 20. Textile Actuator Fibres : Investigation in materials and methods for coiled polymer fibre muscles

    University essay from Akademin för textil, teknik och ekonomi

    Author : Rebecca Melvinsson; [2015]
    Keywords : Textile actuators; Soft robots; Coiled muscles; PVDF; SMP; Fibre Anisotropy; Thermal actuation; α-relaxation;

    Abstract : This thesis contains an investigation in materials and methods for coiled polymer muscles where the end application in mind is to be integrated in a textile structure such as an exo-skeleton glove. Previous artificial muscle fibres have proved little success due to performance, cost and scalability. READ MORE
