1. The effect of taper on pile shaft bearing capacity : Finite element analysis of a tapered wooden pile in sulfate soil
University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserAbstract : he usage of piles, especially wooden piles, have been going on for thousands of years in construction and foundation reinforcements. Sometimes this was done temporary like the Romans who used wooden piles to construct bridges in Britain, or more permanently like the piles upon which the floating city of Venice stands. READ MORE

3. Develop Optimization Model for Spheroidal Graphite Iron
University essay fromAbstract : The main motivation behind this study is to develop a methodology to generate surrogate model coefficients for parametrized Spheroidal Graphite Iron (SGI) for thermal expansion and Young’s modulus response. To accomplish this objective, a 3D model was created by Abaqus, and Python was used for developing the script. READ MORE

5. Development of a Method to Measure Residual Stresses in Cast Components with Complex Geometries
University essay from KTH/MaterialvetenskapAbstract : Cast iron, taking the advantages of the advanced castability forming components of complex geometries and favorable mechanical properties, is employed in engine components in truck industries. Compacted graphite iron (CGI) integrates both merits of lamellar graphite iron (LGI) and spheroidal graphite iron (SGI) such as good machinability and high thermal conductivity from LGI, high ultimate tensile strength (UTS), good fatigue resistance, high elastic modulus, and high ductility from SGI, thus is now becoming a competitive alternative of traditional LGI in cylinder blocks and heads.
