  1. 1. Modelling and simulation of vibratory driven sheet piles - Development of a stop criterion

    University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

    Author : Johannes Jonsson; Anton Andersson; [2021]
    Keywords : Vibratory driving; sheet pile; Technology and Engineering;

    Abstract : During excavations, steel sheet piles are often installed through vibratory driving, to establish a retaining wall that resists soil instability and ground water leakage. The method of vibratory driving is that the sheet pile is driven into the soil with a vertical vibratory motion. This is especially effective in soft soils. READ MORE

  2. 2. Numerical simulations of shear reinforced concrete beams subjected to blast loads

    University essay from KTH/Betongbyggnad

    Author : Anton Frank; Andreas Fristedt; [2021]
    Keywords : Numerical simulations; shear reinforcement; blast loads; dynamic shear failure; Numeriska simuleringar; tvärkraftsarmering; luftstötvåg; dynamiskt skjuvbrott;

    Abstract : Historical accidents and experimental investigations have made apparent that blast loaded concrete members are prone to fail in brittle shear rather than a ductile flexure mode. Air blasts from accidental detonations or explosives may cause severe damage to buildings and infrastructure and it is of great importance that load carrying members can withstand the impulse that arise to avoid progressive collapses.

  3. 3. New encapsulation concept for robot controller cabinet

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Siyu Guo; [2020]
    Keywords : ABB Robotics; Electrical knockout; Explicit dynamics; FEM; Robot controller cabinet; ABB Robotik; Elektrisk knockout; Explicit dynamik; FEM; Robot styrskåp;

    Abstract : Robot controller cabinets are specified with interfaces which make it possible to connect different modules for completing numerous tasks that are chosen for the robot manipulators. Different interfaces will be utilized depend on the kind of tasks and settings that are chosen. READ MORE

  4. 4. CAE modelling of cast aluminium in automotive structures

    University essay from Linköpings universitet/Mekanik och hållfasthetslära; 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.

  5. 5. 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.
