  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. Verification of elastomer characteristics in electro-mechanical linear actuator

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

    Author : Rohit Karmungikar; [2022]
    Keywords : ANSYS; Aging; Hyperelastic; MATLAB and Mooney-Rivlin; ANSYS; Åldrande; Hyperelastic; MATLAB och Mooney-Rivlin;

    Abstract : Cascade Drives develops electromechanical actuators using a rack and pinion configuration to achieve a combination of high load and high-speed operation. A patented load distribution mechanism enables the use of multiple pinions on a single rack, resulting in a compact unit with high positional accuracy capable of absorbing shock loads. READ MORE

  5. 4. Simulation of ultrasonic time of flight in bolted joints

    University essay from KTH/Hållfasthetslära

    Author : David Chlebek; [2021]
    Keywords : Acoustoelastic effect; User material subroutine; Murnaghan hyperelastic material model; Explicit FEM; Ultrasonic preload; Fortran; Akustoelastiska effekten; Användar material; Murnaghan hyperelastisk materialmodell; Explicit FEM; Ultraljudsmätning av klämkraft; Fortran;

    Abstract : Ultrasonic measurements of the preload in bolted joints is a very accurate method since it does not depend on the friction and other factors which cause difficulties for common methods. The ultrasonic method works by emitting an ultrasonic pulse into the bolt which is reflected at the end and returned to the transducer, the change in the time of flight (TOF) can be related to the elongation of the bolt and therefore the preload.

  6. 5. Structural analysis of thermal interface materials and printed circuit boards in telecom units - a methodology

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Mattias Good; [2016]
    Keywords : hyperelastic; viscoelastic; fem; finite element method; telecom; cooling; solid mechanics; nonlinear; uniaxial compression; printed circuit board; pcb; polymer; rubberlike; filled silicone rubber; gappad; thermal pad; mullins effect; cyclic loading; stress softening;

    Abstract : En struktur analys på Ericssons MINILINK-6352 har utförts för att undersöka spänningar och deformationer på enheten, främst med fokus på de termiska gränskiktsmaterialen och buktningar av kretskortet. Dessa är viktiga aspekter när man överväger om enheten är termiska lämpad ur en mekanisk synvinkel, där god ytkontakt mellan de olika kropparna är avgörande för ordentlig kylning genom värmeledning.
