Cristina Beldica, Harry Hilton, Seid Koric & David O’Neal - UIUC NCSA Nicholas Pagano - AFRL David Veazie - Clark Atlanta U Jack Vinson - U of Delaware Sung Yi - Nanyang Technological U, Singapore CSM 5: AEROELASTIC, PIEZO-VISCOELASTIC & STRUCTURAL CONTROL OF COMPOSITE FLIGHT STRUCTURES University of Illinois at Urbana-Champaign
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
CSM 5: Viscoelastic Material & Piezoelectric Damping
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
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
CSM 5: Aeroelasticity with Piezo-Viscoelastic Control
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
CSM 5: Analytical & Experimental Material Property Determinations
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

CSM Predictions of Aircraft Wing Damage due to Ballistic Impact Grand Challenge Proposal J. Calcaterra - VAVS R. Hinrichsen - Anteon Corp. A. Palazotto - AFIT B. Baron - AFRL H. Hilton - UIUC NCSA
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.
CSM 6: Portability and Performance Improvement of the Micromechanics Damage Models (MDM) A CSM PTES Project Proposal Cristina Beldica, David O’Neal - UIUC NCSA Richard Luczak - Rice U Nicholas Pagano - AFRL
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 project’s 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.

OSC Multiscale Materials Modeling A CCM-CSM Proposal for Multidisciplinary and Multisite Collaboration University of Illinois at Urbana-Champaign
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.
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
