Fatigue behavior of notched carbon epoxy laminates during reversed cyclic loads
… by Thermal Emission, was implemented to obtain full-field measurements of surface stresses during damage initiation and growth. A new micromechanical theory of the adiabatic thermoelastic effect in Iaminated fiber composites was conceived to assist the interpretation of SPATE measurements.

Implementation of an Open-Source Digital Image Correlation Software for Structural Testing
… testing utilizing two-dimensional (2D) DIC measurements. DIC is a non-contact optical measurement technique that uses computer vision to track unique attributes on the surface of an object. For structural testing, traditional instrumentation such as displacement sensors and strain gages are …

On-line Nonlinear Characterization of Anisotropic Materials
… behavior of anisotropic materials on-line using full-field strains, which are capable of capturing the multi-axial information of anisotropic materials. A stochastic method is developed to characterize the linear behavior of anisotropic materials under the influence of full-field strain …

Relating fatigue crack growth to microstructure via multiscale digital image correlation
… for this task since it provides quantitative full-field deformation measurements at multiple length scales. The first part of this work introduces two DIC-based techniques for measuring fatigue crack closure levels and demonstrates them on titanium. At the macroscale, a least squares …

Spatially resolved measurements of kinematics and flow-induced birefringence in worm-like micellar solutions undergoing high rate deformations
… System, CRi., Inc.) was adapted for making full-field measurements of flow-induced birefringence (FIB) in order to obtain high-resolution measurements of the evolution of the average stress and molecular conformation in the fluids undergoing strong deformations. First, the shear banding …

Infrared Thermography Techniques for Flow Visualisation and Heat Transfer Coefficient Measurement
… boundary layer state on components and measure full-field heat transfer coefficients. IR cameras are a mature technology; however, the methods for their use in experiments are immature and leave opportunities for improvements. The aim of this thesis is to use a low-order modelling approach to …
