1. 1. Non-Linear strain paths in Sheet Metal Forming

   University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

   Author : Anton Eriksson; [2021]
   Keywords : Sheet metal forming SMF ; Non-Linear strain path NLSP ; Test procedures; Failure models; Finite Element FE ; Plåtformning; Icke-linjära töjningsbanor; Test procedurer; brott model; Finita Element FE .;

   Abstract : Today's automotive requirements have resulted in complex Sheet Metal Forming (SMF) processes of Sheet Metal (SM) with reduced formability, and thus it is crucial to be able to predict formability accurately to prevent material failure during SMF. Formability predictions today utilize Forming Limit Curves (FLC)s in Finite Element Analysis (FEA), but  FLCs are not valid for the Non-Linear Strain Paths (NLSP)s generated during SMF. READ MORE

3. 2. Finite Element Analysis of Stresses in the MIST CubeSat due to Dynamic Loads During Launch

   University essay from KTH/Lättkonstruktioner

   Author : Carl Järmyr Eriksson; [2021]
   Keywords : Satellite; CubeSat; Nanosatellite; Dynamic Loads; Launch Loads; Finite Element Analysis; FEA; Quasi-static Acceleration; Modal Analysis; Random Vibration; Shock Loads; satellit; CubeSat; nanosatellit; dynamiska laster; uppskjutningslaster; finita elementmetoden; FEM; kvasistatisk acceleration; modalanalys; stokastiska vibrationer; chocklaster;

   Abstract : A finite element model of the CubeSat MIST was created, in order to assess the stresses that occur in the satellite in response to loads during its launch. Due to size limits of thesoftware used, simplifications had to be made to the geometry of the model. READ MORE

4. 3. Cross-comparison of Non-Linear Seismic Assessment Methods for Unreinforced Masonry Structures in Groningen

   University essay from KTH/Betongbyggnad

   Author : Viktor Peterson; Zihao Wang; [2020]
   Keywords : Non-linear time-history analysis; non-linear pushover analysis; N2- method; equivalent frame model; continuum model; numerical seismic assessment; unreinforced masonry buildings iv;

   Abstract : A large amount of low-rise unreinforced masonry structures (URM) can be foundin Groningen, the Netherlands. More and more induced earthquakes with shortduration have been detected in this region due to gas exploitation. READ MORE

5. 4. Punching shear in concrete flat slabs supported on slender edge steel columns

   University essay from KTH/Betongbyggnad

   Author : Pasha Jalal; Jose Andres Perez; [2020]
   Keywords : Punching shear; ATENA; FEA; precast slab; flat slab; top and foot plate.; Genomstansning; ATENA; FEA; plattbärlag; pelardäck; topp- och fotplåt.;

   Abstract : Punching shear is a failure mechanism caused by concentrated loads, creating a crack pattern that resembles a cone shape or piece of pie starting from the top surface of the slab and prolongs downwards. When the total shear force is greater than the shear resistance of the slab, it may eventually lead to punching shear failure. READ MORE

6. 5. Experiments, analysis and an application of 3D-printed gyroid structures

   University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

   Author : Jonatan Hussmo; Roman Schröder; [2020]
   Keywords : gyroid; test; convergence; simulation; gyroid; test; konvergens; simulering;

   Abstract : The thesis investigates the mechanical properties of gyroid structures through various experiments and simulations. Gyroid structures consist of an intricate mesh of surfaces and can differ in density and cell size. The mechanical properties of the gyroid structure are inevitably dependent on the density. READ MORE
