Damping

• Objective To make use of smart composite
  materials to regulate deformations, stresses
  failure probabilities through structural,
  material and piezoelectric control
• Methodology Multiphase and multidisciplinary
  analytical formulations and computational
  simulations of viscoelastic material and
  piezoelectric constitutive relations and actual
  scientific and engineering problems
• Results Deterministic and probabilistic stress,
  defor-mation and failure solutions for flight
  vehicle metal and composite structures to avoid
  excessive vibrations, noise transmission and
  undesirable aeroelastic effects and to predict
  structural survival times. (See web site)
• Significance Provide realistic modern
  analytical and computational models and protocols
  to dampen un-wanted deformations and noise
  responses and to furnish structural survival
  probabilities and times to failure to be used by
  DoD, ARL and ASC researchers and designers

19
CSM 5 Massively Parallel Piezoelectric /
Viscoelastic Simulations
201,000 DOF FEM

• Objective To formulate and evaluate
  performances of parallel computational protocols
  for linear and nonlinear viscoelastic stress,
  failure and structural control analyses
• Methodology Commercial codes such as ANSYS and
  ABAQUS with modified subroutines are used for
  solving real engineering problems. For nonlinear
  viscoelasticity, new codes have to be written
  because no available commercial software has such
  capabilities
• Results ABAQUS scales well for large number of
  DOF, but needs modifications to run efficiently
  on more than 16 parallel processors (See web
  site)
• Significance Provide realistic modern
  efficient compu-tational protocols for structural
  analysis, survival probabilities and times to
  failure. Of interest to DoD, ARL, ASC industry
  engineers and scientists

20
CSM 5 Aeroelasticity with Piezo-Viscoelastic
Control

• Objective To investigate applicability of
  viscoelastic damping piezoelectric effects,
  torsional divergence, flutter, aerodynamic
  derivatives, aileron effectiveness and
  aerodynamic noise in composite structures
• Methodology Employ analytical tools and large
  scale computational simulations to conduct
  feasibility studies of light weight, low power
  and inexpensive piezo devices to control
  undesirable aeroelastic effects including
  aero-dynamic and structural coupling
• Results Studies demonstrate ability to control
  aeroelastic effects and flight vehicle motion by
  application of simple sensing and actuator
  piezoelectric devices. (See website)
• Significance Provide realistic modern
  analytical and computational models for
  aeroelastic and structural control of composite
  structures. Of interest to DoD, ARL, ASC
  industry engineers and scientists

21
CSM 5 Analytical Experimental Material
Property Determinations

• Objective To investigate influences of ramp
  loading functions and rise time to full load on
  experimental material characterizations through
  computer simulations
• Methodology Employ analytical tools and large
  scale computational simulations to conduct
  feasibility studies of experimental procedures
  for viscoelastic deterministic random material
  characterizations
• Results Loading patterns distinctly affect the
  determi-nation of viscoelastic material
  parameters, leading to possible erroneous or
  misleading characterizations. Procedure for real
  time (not Laplace Transform) characterization is
  developed. (See website)
• Significance Provide realistic and proper
  analytical and computational tools for material
  characterization of advanced composite
  structures. Of interest to DoD, ARL, ASC
  industry engineers,researchers and scientists

22
CSM 5 Viscoelastic Designer Materials

• Objective Analytical formulations
  computational simulations to determine optimum
  anisotropic viscoelastic designer material
  properties to be manufactured to meet specific
  structural service requirements
• Methodology Solutions for composites are
  approached by an inverse method through examining
  individual effects of portions of relaxation
  modulus curves on creep and relaxation responses
• Results A mechanistic understanding of
  viscoelastic responses to loading, moisture and
  temperature histories has been achieved which
  allow the designer to select tailored composite
  materials for actual service conditions.
  Protocols for proper experimental determination
  of material properties have also been formulated.
  (See website)
• Significance Provide modern composite property
  models to allow ASC, ARL, DoD and industry
  engineering designers to select optimum tailored
  materials for specific structural service
  conditions

Pineda - UNM AHPCC
26

• CSM 7 UIUC / NCSA UNM / AHPCC
• Multidisciplinary CSM Outreach Program
• A two stage approach will be used to accomplish
  the project objective.
• First, a one day symposium will be organized
  featuring presentations by AHPCC and NCSA CSM
  teams augmented by research groups from AFRL
  Phillips AFB WPAFB. Targeted applications will
  include aeroelasticity, composite structures,
  fracture mechanics, aerodynamics,
  multidisciplinary optimization and multiscale
  models.
• Secondly, a cross site project plan will then be
  completed by the NCSA and AHPCC teams to benefit
  research groups at Phillips and Wright-Patterson
  AFBs.

28

• CSM 6 Portability and Performance
  Improvement of the
• Micromechanics Damage Models (MDM)
• Execution of the MDM code suite has been
  restricted to HP plat- forms due to a
  fundamental portability problem. A solution to
  this problem was recently discovered by the NCSA
  CSM team and this projects primary objective
  is to assist the AFRL development group in
  implementing portability onto high performance
  computers.
• Focused efforts will resolve portability
  problems while simulta- neously yielding
  significant performance improvements. This is a
  collaborative project involving AFRL developers
  of the MDM codes, NCSA researchers and the PET
  CSM and PTES site leads at ASC.

• Objective Construction of a prototyping tool
  capable of predicting continuum effects in
  composite materials from the molecular properties
  of the constituent materials.
• Methodology The key to this project lies in the
  design of the mechanism used to bridge atomistic
  and continuum scale analysis tools. A materials
  database will also be used to validate new
  results, as well as catalog information
  associated with previous studies.
• Results This project is still in planning.
  Related proposals for resources have been
  completed. Study of existing multiscale bridging
  techniques has been initiated.
• Significance Multidisciplinary collaboration
  involving CCM and CSM CTAs and Clark Atlanta
  University. Huge potential associated with
  virtual prototyping.

CSM 4 Structural Solver for FDL3DI CFD Code

• Objective To integrate a compact portable 3D FE
  structural solver into the FDL3DI CFD code in
  order to predict flexible aircraft responses to
  aerodynamic loads and to properly couple
  aeroelastic phenomena
• Methodology A linear elastic FE solver is
  being integrated into a high fidelity CFD code
  replacing the previous 1D modal solver
• Results Linear elastic solvers are much more
  accurate than modal solvers in predicting
  structural responses of aircraft subjected to
  aerodynamic loads
• Significance Provide accurate and realistic
  structural responses for aircraft under various
  aerodynamic loads and structural stiffnesses

CSM 2 Visualization and Job Monitoring of
FDL3DI

• Objective To build a portable infrastructure
  for monitoring the progress of FDL3DI jobs during
  simulations
• Methodology CUMULVS will be integrated into the
  FDL3DI code to provide analysts with snapshots of
  job progress during simulations
• Results Many codes (i.e., EPIC and FDL3DI)
  require many days to perform a typical
  simulation. With CUMULUS jobs may be monitored
  throughout the computation to determine accuracy
  of results or to restart with different physical
  parameters.
• Significance Provides a substantial increase in
  HPC resource efficiency and allows the analyst to
  improve results by check pointing and restarting
  a job based on real time examination of results
