Heterogeneous Peridynamic Neural Operators: Discover Biotissue Constitutive Law and Microstructure From Digital Image Correlation Measurements

no code implementations27 Mar 2024 Siavash Jafarzadeh, Stewart Silling, Lu Zhang, Colton Ross, Chung-Hao Lee, S. M. Rakibur Rahman, Shuodao Wang, Yue Yu

Then, in the second phase we reinitialize the learnt bond force and the kernel function, and training them together with a fiber orientation field for each material point.

MetaNO: How to Transfer Your Knowledge on Learning Hidden Physics

no code implementations28 Jan 2023 Lu Zhang, Huaiqian You, Tian Gao, Mo Yu, Chung-Hao Lee, Yue Yu

Gradient-based meta-learning methods have primarily been applied to classical machine learning tasks such as image classification.

A Bayesian constitutive model selection framework for biaxial mechanical testing of planar soft tissues: application to porcine aortic valves

no code implementations26 Sep 2022 Ankush Aggarwal, Luke T. Hudson, Devin W. Laurence, Chung-Hao Lee, Sanjay Pant

Although the model that best fits the experimental data can be deemed the most suitable model, this practice often can be insufficient given the inter-sample variability of experimental observations.

A Physics-Guided Neural Operator Learning Approach to Model Biological Tissues from Digital Image Correlation Measurements

1 code implementation1 Apr 2022 Huaiqian You, Quinn Zhang, Colton J. Ross, Chung-Hao Lee, Ming-Chen Hsu, Yue Yu

To improve the generalizability of our framework, we propose a physics-guided neural operator learning model via imposing partial physics knowledge.

Learning Deep Implicit Fourier Neural Operators (IFNOs) with Applications to Heterogeneous Material Modeling

1 code implementation15 Mar 2022 Huaiqian You, Quinn Zhang, Colton J. Ross, Chung-Hao Lee, Yue Yu

In this work, we propose to use data-driven modeling, which directly utilizes high-fidelity simulation and/or experimental measurements to predict a material's response without using conventional constitutive models.
