Paper Abstract

This work describes the results of experimental and analytical studies conducted in a project to identify the requirements for correlation between experimental displacement measurement data and finite element analytical displacement estimation. The work attempts to define fundamental requirements for both test and analysis that would improve correlation potential. An in-plane sensitive Electronic Speckle Pattern Interferometer (ESPI) is the experimental method and a Finite Element Method (FEM) is the analytical one. The impact of proper experimental setup and instrument design, rigid body control, and loading problems are discussed. An assessment of the minimum FEM modeling details has also been provided.
