摘要

将实验数据整合到模拟中对于预测材料行为至关重要，尤其是在断裂力学中。数字图像相关（DIC）可提供精确的位移测量数据，对于评估裂纹周围的应变能释放率和应力强度因子（SIF）至关重要。它使用 J 积分法计算 SIF，无需试样几何形状或施加载荷即可处理复杂情况。DIC2CAE 提高了断裂力学模拟的可靠性，加速了材料研究与开发。

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

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.
