Abstract

A Digital Image Correlation method is used to study a compression test carried out on crimped glass wool samples to determine the displacement field, which reveals strain heterogeneities and further localization. The structure of the wool is locally strongly anisotropic, even though the preferential orientation varies significantly in space. This structure is analyzed using an ad hoc orientation detection tool. It is shown that the strain amplitude can be correlated with texture gradients for this type of material.
