Nonlinear Structural Mechanics and Aeroelasticity
Mayuresh Patil, Virginia Tech
The presentation will include selected research topics from
nonlinear structural mechanics, nonlinear aeroelasticity and flight
dynamics of flexible aircraft. In the nonlinear structural mechanics
area, the focus of the talk will be on nonlinear beam theory as applied
to helicopter blades and high-aspect-ratio wings. The topics covered
will include geometrically-exact formulation, fully-intrinsic equations
and various approaches to solving the equations. The presentation will
briefly introduce ongoing work on geometrically-exact plate equations
and equations for large deformation analysis of membrane and inflatable
structures. The second part of the talk will focus on nonlinear
aeroelasticity of high-aspect-ratio wings as well as the flight dynamics
of flexible flying-wing aircraft. The presentation will describe a
geometrically-consistent methodology to couple aerodynamic models to
nonlinear structural models and ongoing work on gust response
prediction. The talk will end with a look at future work and
collaborative possibilities.
