Digital image correlation

TL;DR: This study presents a novel experimental approach to the characterization of the deformation of a mineralized biological composite using arthropod cuticle as a model material by performing tensile tests combined with a detailed strain analysis via digital image correlation of the endocuticle of the American lobster Homarus americanus.

TL;DR: A Digital Image Correlation-based single camera pseudo-stereo system that uses a biprism in front of the camera objective to split the scene into two equivalent lateral stereo views in the two halves of the sensor is presented and tested.

TL;DR: In this article, two physically-based methodologies, a timedependent method and a time position-dependent method (called here flat-valley method), were used to detect the onset of necking and evaluate the limit strains under significant strain gradients through the sheet thickness.

TL;DR: In this article, a relatively simple nonlinear viscoelastic constitutive model for particle-filled rubber under three-dimensional stress states is developed from an existing axisymmetric constitutive equation and then experimentally verified.

TL;DR: In this article, a method combining acoustic emission (AE) signals with digital image correlation (DIC) was used to monitor compressive buckling behaviors of delamination composites.
