Self-adaptive Subsets for Stretched and Rotated Textures in Digital Image Correlation

Creator:: Gao, Zizhan
Abstract:: Digital image correlation (DIC) uses pairs of images, one in a reference state and one after in situ manipulation of the object, to measure full-field displacements and strains by tracking the motion of small image subsets. Subset selection is always a crucial part of DIC technique as it has a...

Mechanical linkage design for haptic rehabilitation and development of fine motor skills

Creator:: Streng, B. Taylor
Abstract:: Thousands of children and adults suffer from fine motor skill deficits due to developmental disabilities or brain trauma. In order to acquire or reclaim these precision motor movements, occupational therapists work closely with each patient to develop the muscle memory required for completing tasks such as handwriting or drawing. Although...

Usage of Digital Image Correlation in Single and Multiple Stereo Systems for Strain and Shape Measurement

Creator:: McKinley, Timothy A.
Abstract:: This dissertation details the application of digital image correlation (DIC) in novel methods for mechanical testing and shape characterization. The first usage manifested in the development of a novel composite test specimen that provided the ability to characterize the matrix compression energy release rate at initiation and subsequent crack propagation....

Quantitative comparison of full field strains experimentally measured and analytically predicted for aluminum foams

Creator:: Rutschman, Scott A.
Abstract:: Metallic foams have become widely available and have unique properties that make them attractive for use in a variety of engineering applications. Due to their complex structure, the behavior of foams under complex loading conditions is a subject of continued research. Digital volume correlation is a technique wherein full-field strains...

Achilles Assistance Device as a Passive Ankle Foot Orthosis for Achilles Tendon Injuries

Creator:: Gonnerman, Evan J.
Abstract:: An Achilles tendon injury can be devastating. Surgical methods to bring the muscle to full strength are not always available. Proposed is an ankle foot orthosis (AFO) that is entirely passive (does not add energy to the system) and uses the mechanical advantages provided by the walking gait of a...

Evaluation of total hip arthroplasty research in the US and Europe

Creator:: Simmons, Marcy J.
Abstract:: Background: Hip replacements are considered routine operations which improve the quality of life in patients by reducing pain and restoring function. There are many variations in prostheses with varying benefits and disadvantages. Methods: Literature from the United States and Europe was collected on total hip replacements between 2001 and the...

Quantification of total and plastic 3D strain fields within micro-damaged polyurethane foam

Creator:: Sutton, Matthew T.
Abstract:: Local material damage that occurs within cellular solids, such as polymer foams and trabecular bone, and precedes local fractures of the cell struts or walls is called micro-damage. The accumulation of micro-damage within cellular solids is often undesirable, although it is thought to be vital to the development and health...

Functional imaging reveals modest strain concentrations associated with implant micromotion using modified BAK interbody cages

Creator:: Berry, Daniel J.
Abstract:: Interbody fusion cages are increasingly used in the treatment of spinal disease and injury in order to stabilize movement and promote arthrodesis of the vertebral bodies, but the micro-mechanics of the interaction between the cage and the adjacent host bone is not fully understood. This information has bearing on post-surgical...

Influence of subset size, shape and orientation on texture based digital image correlation

Creator:: Cui, Jianqing
Abstract:: Digital Image Correlation(DIC) is one of full-field strain measurement techniques devel- oped in recent decades, which has been well-demonstrated to conduct the mechanical properties study of solid materials, by collecting data using digital cameras. X-ray to- mography(CT) imaging helps the correlation techniques expanded to three dimensional investigation of materials, known...

Elastic, plastic, and total strains in human and porcine pedicle trabecular bone and PU-foam after pedicle screw insertion by utilizing functional micro-CT imaging

Creator:: Moran, Sean T.
Abstract:: Pedicle screw breakage and loosening remain as clinical complications of short segment instrumentation procedures for spinal stabilization. This study has directly visualized and measured elastic, plastic and total vertebral pedicle trabecular bone full-field strains in the regions immediately surrounding the pedicle screw during pedicle screw insertion by utilizing functional microCT...
