  2. 2. Inflation Mechanics of Hyperelastic Membranes

    Author : Amit Patil; Anders Eriksson; Arne Nordmark; Reijo Kouhia; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Membrane Mechanics; Inflation; Adhesive Contact; Instabilities; Bifurcation; Limit Point; Teknisk mekanik; Engineering Mechanics;

    Abstract : The applications of inflatable membrane structures are increasing rapidly in the various fields of engineering and science. The geometric, material, force and contact non-linearities complicate this subject further, which in turn increases the demand for computationally efficient methods and interpretations of counter-intuitive behaviors noted by the  scientific community.

  3. 3. Novel RF MEMS Switch and Packaging Concepts

    Author : Joachim Oberhammer; KTH; []
    Keywords : 0-level packaging; adhesive bonding; BCB; benzocyclobutene; bond strength; contact printing; film actuator; glass lid encapsulation; glass lid packaging; helium leak test; hermetic packaging; hermeticity; high isolation switch; low stress silicon nitride; low volt; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Radio-frequency microelectromechanical systems (RF~MEMS) are highly miniaturized devices intended to switch, modulate, filter or tune electrical signals from DC to microwave frequencies. The micromachining techniques used to fabricate these components are based on the standard clean-room manufacturing processes for high-volume integrated semiconductor circuits. READ MORE

  4. 4. Adhesive wear testing and modelling of tool steels sliding against sheet metals

    Author : Fredrik W. Lindvall; Jens Bergström; Pavel Krakhmalev; Mikael Olsson; Karlstads universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Adhesive wear; Materialteknik; Materials Engineering;

    Abstract : Sheet metal forming is a manufacturing method used because of its versatility. Sheets are plastically deformed by a tool to create a product. A tool is expected to last for several 100,000 forming operations and efforts are made to optimize the tools. A common type of wear referred to as galling is the adhesion of sheet material to the tools. READ MORE

  5. 5. Contact allergens in p-tert-butylphenol-formaldehyde resin

    Author : Erik Zimerson; Yrkes- och miljödermatologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Dermatology; main allergens; structure-activity relationships; identification of contact allergens; guinea pig maximization test; p-tert-butylphenol-formaldehyde resin; patch testing; venereology; Dermatologi; venereologi;

    Abstract : p-tert-Butylphenol-formaldehyde resin (PTBP-F-R) is used as a binder in many adhesive formulations and it consists of a complex mixture of substances, most of which are unknown. The resin has been reported to cause allergic contact dermatitis since the 1950s. READ MORE
