ABSTRACT:

The advancements in both the computational capabilities and the
manufacturing technologies allow us to employ nature-inspired stiffening
members in aircraft wing skin panel design for improving structural
performance. Nevertheless, these shape structures increase the complexity
of the studied models, resulting in a highly complex modeling problem in
design analysis when using traditional approaches. For a robust and cost
effective structural analysis, separating modeling approaches were proposed
for modeling stiffening members and wing skin panels separately when using
curved stringers and curved fiber path of tow-steered laminates. The local
approximation method using finite element isoparametric shape function and
the global approximation method using radial basis function in
skin-stringer assembly are both studied. Curved stiffeners and tow steered
laminates are able to tailor buckling mode shape and redistribute the
in-plane load resultants, respectively, for improving buckling performance
of structures subjected to both thermal and mechanical loads. Structural
optimization was conducted to further demonstrate the benefit of using
nature-inspired curvilinear stiffening members to design highly stiffness
tailorable yet lightweight structures.

Bio:

Dr. Wei Zhao is currently a Research Associate in the Kevin T. Crofton
Department of Aerospace and Ocean Engineering at Virginia Tech. He received
his Ph.D. in Aerospace Engineering at Virginia Tech in August 2017. Dr.
Zhao’s research focus is on composite structures, inflatable wings,
aeroelasticity and multidisciplinary design optimization. He has published
11 journal articles, 8 of them as the first-author, on aerospace structures
and novel-concept airplane designs. In addition, he has published more than
20 conference papers in various American Institute of Aeronautics and
Astronautics (AIAA) organized conferences; two of which were by invitation
in the AIAA SciTech forum. His research work on composite airplane design
has been reviewed in Aerospace America annual review in 2017 and 2019. Dr.
Zhao is a professional member of AIAA. He has also chaired an AIAA SciTech
2021 forum session on composite structural design, analysis and tests. He
is now serving as a topic editor on composite laminated structures for
Journal of Composite Science.
