1. 1. 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. 2. Mechanical Behaviour of Single-Crystal Nickel-Based Superalloys

   University essay from Hållfasthetslära; Tekniska högskolan

   Author : Daniel Leidermark; [2008]
   Keywords : material model; single-crystal; superalloy; crystal plasticity; LS-DYNA; ABAQUS; FORTRAN; pole figure;

   Abstract : In this paper the mechanical behaviour, both elastic and plastic, of single-crystal nickel-based superalloys has been investigated. A theoretic base has been established in crystal plasticity, with concern taken to the shearing rate on the slip systems. READ MORE
