1. Method Development & Analysis of Seals using FEM
University essay from KTH/MaskinkonstruktionAbstract : 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

2. Fracture simulation with a hyperelastic phase field model
University essay from KTH/HållfasthetsläraAbstract : 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.

3. Verification of elastomer characteristics in electro-mechanical linear actuator
University essay from KTH/Skolan för industriell teknik och management (ITM)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

4. Simulation of ultrasonic time of flight in bolted joints
University essay from KTH/HållfasthetsläraAbstract : 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.

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 matematikAbstract : 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.
