| Description: |
| |
This mini-symposium consists of a track of four sessions dealing
with functionally tailored structures for extreme thermo-acoustic
environments. The session titles and descriptions are:
1) Numerical Simulation of Functionally Graded Materials
This session would focus on simulation of functionally graded materials
on a microscopic basis. Multi-scale and computational issues could
be addressed as well as probabilistic methods to predict the response
of functionally tailored structures to extreme thermo-acoustic environments.
Other topics include modeling the effect of residual stresses, crack
initiation, failure mechanisms and fatigue.
2)Analytical and Modeling Aspects of Functionally Tailored Structures
for Extreme Thermo-acoustic Environments
This session will focus on methods of modeling functionally tailored
structures for the combined extreme environment. This would include
but is not limited to the dynamic response at high temperature using
analytical, finite element, boundary element, modal or reduced order
modal methods. Other topics include modeling the effect of residual
stresses, crack initiation, failure mechanisms and fatigue, optimal
structures as well as high speed impact.
3)Verification and Validation of Functionally Tailored Structures
for Extreme Thermo-acoustic Environments
This session will look at methods of verifying and validating modeling
methods for functionally tailored structures. This includes experimental
and benchmark solutions for response, strength, residual stresses
and lifetimes in the combined thermo-acoustic environment. Testing
of numerically derived optimal structures could also be included.
4)Implementation, Risk and Reliability Functionally Tailored Structures
for Extreme Thermo-acoustic Environments.
This session will examine methods of implementing functionally graded
structures in the combined thermo-acoustic environment as well as
ways to determine risk and reliability. Identification of unique
aspects of probabilistics with regard to functionally graded structures
and materials. Sources of uncertainty associated with material processing,
manufacturing and service life are welcome. |
