The Grid Method for In‐plane Displacement and Strain Measurement: A Review and Analysis
The grid method is a technique suitable for the measurement of in‐plane displacement and strain components on specimens undergoing a small deformation. It relies on a regular marking of the surfaces
Evaluation of Methodologies for Compensation of Out of Plane Motions in a 2D Digital Image Correlation Setup
In 2D digital image correlation, out of plane motions are an important experimental factor to consider. Because a 2D setup does not provide any depth information, movements towards the camera (out of
Large-strain Soft Sensors Using Elastomers Blended with Exfoliated/Fragmented Graphite Particles
An elastic polymer (e.g., PDMS) blended with EFG particles is a promising conductive composite for fabricating soft sensors that can detect an object's deformation up to or more than 50%. Here, we
Parameter study of microwave assisted exfoliation of graphite and its application to large deformation strain sensors
Exfoliated graphite (EG), when blended into elastomer, is a promising material for the fabrication of large deformation strain sensors that can detect large deformation up to or more than 50%. Much,

System response to automated grid methods
TLDR
A start-to-finish analysis of grid point tracking with image acquisition hardware and pattern recognition software shows that the intensity profile of the individual grid spots has a significant impact on the maximum allowable grid frequency, camera field of view, and the overall aceuracy of automated grid methods.
