DIC2CAE: Calculating the stress intensity factors (KI-III) from 2D and stereo displacement fields

Abstract

Integrating experimental data into simulations is crucial for predicting material behaviour, especially in fracture mechanics. Digital Image Correlation (DIC) provides precise displacement measurements, essential for evaluating strain energy release rates and stress intensity factors (SIF) around cracks. Translating DIC data into CAE software like ABAQUS has been challenging. DIC2CAE, a MATLAB-based tool, automates this conversion, enabling accurate simulations. It uses the J-integral method to calculate SIFs and handles complex scenarios without needing specimen geometry or applied loads. DIC2CAE enhances fracture mechanics simulations' reliability, accelerating materials research and development.
