1. 1. Method Development & Analysis of Seals using FEM

   University essay from KTH/Maskinkonstruktion

   Author : Lovisa Svanborg Östlin; [2023]
   Keywords : FEM; guidelines; hyperelastic materials; hyperelastic material models; method development; seals; FEM; riktlinjer; hyperelastiska material; hyperelastiska materialmodeller; metodutveckling; tätningar;

   Abstract : Hyperelasticity is a significant property of rubber, taken advantage of in engineering applications. A common application is the use of seals to prevent fluid transfer (liquid or gas) between solid regions. Volvo CE is often depending on external supplier when developing seals. READ MORE

3. 2. Fracture simulation with a hyperelastic phase field model

   University essay from KTH/Hållfasthetslära

   Author : Adrien Fradet; [2023]
   Keywords : Fracture; Phase field modeling; Hyperelasticity; Brott; fasfält-methoden; hyperelasticite;

   Abstract : The phase field method is a versatile tool to study crack initiation and propagation in systems with complex geometries. Based on a variational formulation of the equilibrium equations, the sharp crack topology is regularized by a crack with diffusive edges and the damage is described by a continuous phase field variable.

4. 3. Test and Calibration of CUBES: a CubeSat X-ray Detector

   University essay from KTH/Fysik

   Author : Caroline Holmberg; [2022]
   Keywords : Applied Physics; Astroparticle Physics; Tillämpad fysik; Astropartikelfysik;

   Abstract : CUBES is an X-ray detector that will be placed aboard the KTH 3U CubeSat mission, MIST. Its purpose is to detect high energy X-rays as well as to test various components in a space environment. Two CUBES will be placed on the satellite. Each CUBES consists of a printed circuit board (PCB) with three multi pixel photon counters (MPPCs). READ MORE

5. 4. Development of a Method to Determine the Influence of Rubber Components in Dynamic Simulations

   University essay from KTH/Farkostteknik och Solidmekanik

   Author : Mårten Vuorinen; [2022]
   Keywords : ;

   Abstract : In order to make sure that an engine can withstand the vibration loads, while the weight is kept as low as possible, some components on the engine are made of rubber. The stiffness of these rubber components are several orders of magnitude lower than the surrounding metal components, and the inclusion of rubber components affects the dynamic behaviour of the engine.

6. 5. Effects of Temperature and Moisture Content on Young’s Modulus in Glass Fiber Reinforced Polyamide

   University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

   Author : Joel Sandberg; Samuel Sjölin; [2022]
   Keywords : Polyamide; nylon 66; PA66GF25; glassfiber reinforced polyamide; Young’s modulus; Polyamid; nylon 66; PA66GF25; glasfiberförstärkt polyamid; Youngs modul.;

   Abstract : This thesis was made in cooperation with Roxtec. Roxtec specialises in cable sealingsolutions and are world leading in their area. In many of Roxtec’s products steel isused in the frame holding the sealing rubber. To lower Roxtec’s environmental foot-print plastic would be used instead in the frames if possible, more specific polyamide6. READ MORE
