Advanced Tools for Design and Analyses of High Temperature Cyclic Loaded Turbine Components
  U. Gampe, I. Martynov, J. Keyser
  "The paper presents a new concept to predict viscoplastic deformations in components under thermal mechanical loading. This approach is based both on material data from uniaxial creep tests and additional laboratory component tests to consider the influence of multiaxiality. This concept was used for analysis of feature tests of flat tensile specimens with central hole. The maximum test temperature was 600 °C and the surface of the hole was attacked by cyclic thermal shocks." (This paper refers to use of ANSYS User-Defined Materials. A related paper is Laboratory Component Testing for Investigation of Material Degradation from Creep-Fatigue Interaction.)

An Architecture for Fluid/Structure Analysis of Turbomachinery Blading
  David A. Johnston, Charles J. Cross, J. Mitch Wolff
  "Aeroelastic stability and response analyses used in the design of turbomachinery blading are typically uncoupled: the unsteady aerodynamics and structural dynamics are treated in separate models, with boundary conditions sequentially updated after stationary periodic convergence is met. Higher fidelity simulations are achieved by coupling the fluid and structure domains such that boundary conditions are updated once or several times per physical time step of the simulation." "As a starting point, the turbomachinery CFD research code TURBO (Chen and Briley, 2001) and the commercial structural solver ANSYSŪ has been chosen for coupling, although FSI is designed with modularity for future inclusion of other fluid and structural solvers."

An Interpretation of the Physics of Fluid-Structure Interaction in the Frequency Domain
  Jan Christian Anker
  "This paper constitutes an attempt to interpret the physics of FSI where the structure is vibrating. The structure considered is a very simple physical device, namely a flat cantilever plate. Many presumably important details are only briefly mentioned, other are left completely out of the discussion. The intention with the paper is to emphasize that there are cases where Fluid - Structure Interaction can be successfully simulated without having to utilize a Navier-Stokes Solver coupled with a (non-linear) Structural Analysis Program, a concept that requires vast amounts of computer time for linear vibrations (but is highly relevant for other applications)."

Creep Resistance and Creep Bending Resistance of Light Metal Matrix Composites for Research in Airframe Structural Effiency
  E. Neubauer and H.Peter Degischer
  "Main aim of the research in the frame of the AMTT programme was the testing of a fiber reinforced Al-alloy. For investigation of the creep behaviour of this material, creep tests under bending were performed. The tested material was Al99.85+0.1%Mg reinforced with Al2O3 fibers (Altex/Sumitomo), which was prepared by means of gas pressure infiltration. Main benefit of such a material for application would be the lowering of the weight of the material without a loss of properties." (see Appendix A for ANSYS use in this document)
