On the use of optical methods in the validation of non-linear dynamic simulations of sandwich structures

Innovative designs of transport vehicles need to be validated in order to demonstrate reliability and provide confidence. The most common design approach of such structures involves simulations based on Finite Element (FE) analysis, which require reliable validation techniques, especially if anisotropic materials, or complex designs, such as sandwich panels are to be applied. The present paper aims to integrate sophisticated numerical analysis with full-field optical measurement system data in order to improve the quality of both methods and increase reliability of the design.
