Abstract

Structures operating in aero-thermal environments greater than the speed of sound will experience large pressure and temperature gradients over small areas due to shock-wave impingement in addition to large amplitude distributed acoustic and/or mechanical loading from vehicle dynamics. Such combined environments complicate the dynamic response of these structures since the localized thermal loading affects their global dynamic response. This work experimentally explores the static and dynamic response of a 248 mm x 400 mm curved stainless steel panel subjected to localized thermal loading and distributed mechanical loading. The linear and nonlinear dynamic response of the panel is measured with high-speed 3D digital image correlation, and the temperature distribution is measured with a Forward Looking InfraRed camera. The resulting data set demonstrates how localized heating affects global dynamics in linear and nonlinear regimes.
