Basics of Linear ThermoelasticityMeyer, Arnd, Springer, Rolf 06 February 2015 (has links) (PDF)
In this preprint, we look onto the theory of linear thermoelasticity. At the beginning, this theory is shortly repeated and afterwards applied to transversely isotropic materials. Then, the corresponding weak formulation is derived, which is the starting point for a FE-discretisation. In the last part, we explain how we added this material behaviour to an adaptive Finite-Element-code and show some numerical results.

Grundgleichungen für transversal isotropes Materialverhalten / Basic Equations for Transversely Isotropic MaterialWeise, Michael, Meyer, Arnd 02 November 2010 (has links) (PDF)
In diesem Preprint werden grundlegende Gleichungen zur Behandlung von transversal isotropem Materialverhalten zusammengetragen. Wir betrachten ein transversal isotropes Materialgesetz mit linear elastischem Verhalten. Die angegebenen Materialgleichungen sind zur Beschreibung sowohl kleiner als auch großer Deformationen geeignet. Sie bilden eine wesentliche Grundlage zur Lösung statischer Probleme mit der Methode der finiten Elemente. Es werden Gleichungen für den ebenen Spannungszustand und den ebenen Verzerrungszustand hergeleitet.

Ionene and ionene alkyl sulfate stoichiometric complexes / Temperature and humidity sensitive materials / Ionene und Stöchiometrische Ionene-Alkylsulfat-KomplexeYu, Quanwei 03 October 2004 (has links) (PDF)
Stoichiometric polyelectrolyte-surfactant complexes represent a type of comb-shaped polymers, in which every polymer chain unit has an electrostatically bound "side chain". These complexes are water-insoluble. In the solid state they assemble spontaneously into mesogenic structures. The [X,Y]-ionenes ([(CH2)XN+(CH3)2(CH2)YN+(CH3)2]nBr-2n) investigated formed stoichiometric complexes with alkyl sulfates. The ionene alkyl sulfate complexes display mesogenicity, i.e. optically isotropic dry complexes underwent lyotropic and thermotropic phase transitions to the optically anisotropic phase (and vice versa) under controlled relative humidity. The optically anisotropic phases exhibited hexagonal textures as revealed by polarizing microscopy. A new feature is the lyotropic transition brought about by the uptake of water through the gas phase. The complexes were all sensitive to both humidity and temperature. In principle, the effects can be applied to measure humidity.
