1. 21. A predictor corrector method for a Finite ElementMethod for the variable density Navier-Stokes equations

   University essay from KTH/Numerisk analys, NA

   Author : Isabel Haasler; [2017]
   Keywords : ;

   Abstract : Constructing Finite Element Methods for the incompressible Navier-Stokes equations that are computationally feasible requires the use of pressure segregation methods such as the predictor corrector scheme. From an algebraic point of view these methods correspond to a preconditioned Richardson iteration on the pressure Schur complement. READ MORE

3. 22. Simulation of fatigue crack growth in coated cemented carbide milling inserts

   University essay from KTH/Hållfasthetslära (Avd.)

   Author : André Tengstrand; [2017]
   Keywords : ;

   Abstract : The aim of this work is to create a nite element model that simulates fatigue crack growth in coated cemented carbide milling inserts. A typical fatigue wear of coated milling tools are comb crack formation on the cutting edges of the tool inserts. Comb cracks initiate from pre-existent cooling cracks in the coating layers.

4. 23. Moisture-induced crack development in timber beams : a parametric study performed on dowelled timber connections

   University essay from Linnéuniversitetet/Institutionen för byggteknik (BY)

   Author : Tadios Sisay Habite; [2017]
   Keywords : Moisture; Crack; Extended finite element; Parametric study;

   Abstract : A problem has been observed by many researchers regarding the cracks caused mainly by moisture variation in timber structures. However, this effect has been neglected over the past decades. READ MORE

5. 24. HEAT TRANSIENT TRANSFER ANALYSIS OF BRAKE DISC /PAD SYSTEM

   University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

   Author : Srivatsan Thuppal Vedanta; Naga Vamsi Krishna Kora; [2016]
   Keywords : Brake disc; Brake dimensioning; Heat transient analysis; Finite Element; Calibration;

   Abstract : Braking is mainly controlled by the engine. Friction between a pair of pads and a rotating disc converts the kinetic energy of the vehicle into heat. High temperatures can be reached in the system which can be detrimental for both, components and passenger safety. READ MORE

6. 25. Finite Element Simulations of Harmonic Structured Materials in Two Dimensions

   University essay from Lunds universitet/Mekanik

   Author : Jakob Salomonsson; [2016]
   Keywords : Technology and Engineering;

   Abstract : Most of today’s materials show either high strength with low ductility, or relatively low strength combined with high ductility. It is strongly desired in the industry to obtain materials whose mechanical properties can display a combination of high strength and elongation. READ MORE
