  1. 1. Crack growth based FEM with embedded discontinuities

    University essay from KTH/Hållfasthetslära

    Author : David Lindblom; [2021]
    Keywords : PUFEM; Fracture Mechanics; J2-plasticity; FEAP; Strong discontinuity; Variational formulation; XFEM; PUFEM; Brottmekanik; J2-plasticitet; FEAP; Diskontinuitet; variationskalkyl;

    Abstract : In recent years there have been a major developments in the computational mechanics community when it comes to modelling of fracture mechanics. There are now several well established numerical methods that are implemented in commercial programs such as: Phase Field Modelling, Enhanced Assumed Strain (EAS), Smeared Crack Methods, Extended Finite Element Method (XFEM) and Partition of Unity Finite Element Method (PUFEM).

  3. 2. Numerical Study on Hydrodynamic Characteristics of Flood Discharge Tunnel in Zipingpu Water Conservancy Project : Using RANS equations and the VOF model

    University essay from Uppsala universitet/Elektricitetslära

    Author : Micaela Hamberg; Signe Dahlin; [2019]
    Keywords : VOF; RANS; Navier-Stokes; Spillway; Discharge tunnel; ANSYS; Fluent; CFD; Grid convergence index; Design of spillway; Cavitation; Gambit; k-epsilon; Ansys Gambit;

    Abstract : To avoid the large amount of damage that floods can cause, spillway tunnels are used to control water levels. To ensure the safety of water transportation through spillway tunnels, the behaviour of the water throughout the tunnel is important to know. READ MORE

  4. 3. Extraction of tool reaction forces using LS-DYNA and its use in Autoform sheet metal forming simulation

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Esbjörn Zachén; [2019]
    Keywords : Sheet Metal Forming; Stamping Die; blank holder; Structural Analysis; Finite Element Simulation;

    Abstract : In product development there is still potential to decrease lead times with faster and more accurate simulations. The objective of this thesis was to study whether Finite Element (FE) simulations using explicit LS-DYNA to extract reaction forces from sheet metal forming tools during forming, could be used to improve existing FE models in sheet metal forming software AutoForm.

  5. 4. Simmulating pullout forces in particleboard

    University essay from Linköpings universitet/Mekanik och hållfasthetslära

    Author : Tapiwanashe Phiri; Niklas Björkman; [2019]
    Keywords : transversely isotropic material; orthotropic material; particleboard; finite element analysis; material model;

    Abstract : Pull-out forces of screws and connectors in particleboard are particularly important when designing for strength and, or assembly in the furniture industry. The aim of this thesis was to develop a simulation model of particleboard that can predict pull-out forces of screws better than the currently used simulation model at IKEA of Sweden. READ MORE

  6. 5. Comparison of Shatter Effects in Autodesk Maya with nCloth and DMM Plugin

    University essay from Avdelningen för Industriell utveckling, IT och Samhällsbyggnad

    Author : Caroline Irwin; [2012]
    Keywords : Shatter Effects; nCloth; DMM Plugin; 3D; Tetrahedral Elements;

    Abstract : In today’s society, movies and videogames with a great deal of visual effects that contain objects that break, shatter or explode are popular. They are created from a number of different kinds of 3D programs and plugins. READ MORE
