Description:

Stress (force) induces the deformation of materials. Stress distribution in materials is generally heterogeneous depending on their shapes and microstructures, which governs their global deformation and failure, and sometimes stress concentration induces serious incidents in society. However, it has been challenging to experimentally quantify stress distributions in materials in macro- and micro-scales by now. Here, we newly propose and establish a simple but promising method to quantify local stress distributions in materials by applying the digital image correlation (DIC) technique, which is applicable to all length scales. We expect that the newly developed method would become the first step to give an impact on fundamentally understanding the deformation and fracture of materials in various scales as well as on practically reducing risks in structural components.
