Inverse Design of Vitrimeric Polymers by Molecular Dynamics and Generative Modeling

no code implementations6 Dec 2023 Yiwen Zheng, Prakash Thakolkaran, Jake A. Smith, Ziheng Lu, Shuxin Zheng, Bichlien H. Nguyen, Siddhant Kumar, Aniruddh Vashisth

Vitrimer is a new class of sustainable polymers with the ability of self-healing through rearrangement of dynamic covalent adaptive networks.

Automated discovery of interpretable hyperelastic material models for human brain tissue with EUCLID

no code implementations25 May 2023 Moritz Flaschel, Huitian Yu, Nina Reiter, Jan Hinrichsen, Silvia Budday, Paul Steinmann, Siddhant Kumar, Laura De Lorenzis

Following the motive of the recently proposed computational framework EUCLID (Efficient Unsupervised Constitutive Law Identitication and Discovery) and in contrast to conventional parameter calibration methods, we construct an extensive set of candidate hyperelastic models, i. e., a model library including popular models known from the literature, and develop a computational strategy for automatically selecting a model from the library that conforms to the available experimental data while being represented as an interpretable symbolic mathematical expression.

NN-EUCLID: deep-learning hyperelasticity without stress data

1 code implementation4 May 2022 Prakash Thakolkaran, Akshay Joshi, Yiwen Zheng, Moritz Flaschel, Laura De Lorenzis, Siddhant Kumar

We propose a new approach for unsupervised learning of hyperelastic constitutive laws with physics-consistent deep neural networks.

Data-driven topology optimization of spinodoid metamaterials with seamlessly tunable anisotropy

no code implementations31 Dec 2020 Li Zheng, Siddhant Kumar, Dennis M. Kochmann

We present a two-scale topology optimization framework for the design of macroscopic bodies with an optimized elastic response, which is achieved by means of a spatially-variant cellular architecture on the microscale.
