  1. 11. FE based method for simulation of rock-loading on a truck

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Tamim Kohestani; Ali Zeaiter; [2019]
    Keywords : FEM; Rock loading; Nastran; LS-DYNA; ANSA; META; Contact; Linear; non-linear; Explicit; Implicit.;

    Abstract : Volvos trucks are used to carry boulders of varying sizes from different mining sites or construction sites. These boulders are loaded onto the dumper of the truck by a wheel-loader which drops the boulders from various heights causing an impulse like force which distributes throughout the frame and to the rest of the truck.

  3. 12. The effect of pre-stressing location on punching shear capacity of concrete flat slabs

    University essay from KTH/Betongbyggnad

    Author : Saeed Vosoughian; [2019]
    Keywords : Concrete flat slabs; Concrete damage plasticity model; Eurocode 2; Nonlinear finite element analysis; Punching capacity; Pre-stressing cables;

    Abstract :         Implementing pre-stressing cables is a viable option aiming at controlling deformation and cracking of concrete flat slabs in serviceability limit state. The pre-stressing cables also contribute to punching shear capacity of the slab when they are located in vicinity of the column. READ MORE

  4. 13. A stable and accurate hybrid FE-FD method

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Tuan Anh Dao; [2019]
    Keywords : ;

    Abstract : We develop a hybrid method to couple finite difference methods and finite element methods in a nonconforming multiblock fashion. The aim is to optimize computational efficiency when complex geometries present. READ MORE

  5. 14. Safety formats for non-linear finite element analyses of reinforced concrete beams loaded to shear failure

    University essay from KTH/Betongbyggnad

    Author : Anton Ekesiöö; Andreas Ekhamre; [2018]
    Keywords : nonlinear finite element analysis; estimation of coefficient of variation; par- tial factor; model uncertainty; deep beams; shear;

    Abstract : There exists several different methods that can be used to implement a level of safety when performing non-linear finite element analysis of a structure. These methods are called safety formats and they estimate safety by different means and formulas which are partly discussed further in this thesis. READ MORE

  6. 15. Experimental and numerical fluid-structure interaction analysis of a suspended rod subjected to forced vibrations

    University essay from KTH/Marina system

    Author : David Ahlsén; [2018]
    Keywords : ;

    Abstract : This study is evaluating Solid-Acoustic Finite Element modelling as a method for calculating structural vibration response in water. When designing for example vehicles, it is important to avoid vibrational resonance in any part of the structure, as this causes additional noise and reduced lifespan. READ MORE
