N-Adaptive Ritz Method: A Neural Network Enriched Partition of Unity for Boundary Value Problems

no code implementations16 Jan 2024 Jonghyuk Baek, Yanran Wang, J. S. Chen

Conventional finite element methods are known to be tedious in adaptive refinements due to their conformal regularity requirements.

Investigating the Correlation between Force Output, Strains, and Pressure for Active Skeletal Muscle Contractions

no code implementations9 Oct 2023 Karan Taneja, Xiaolong He, John Hodgson, Usha Sinha, Shantanu Sinha, J. S. Chen

Experimental observations suggest that the force output of the skeletal muscle tissue can be correlated to the intra-muscular pressure generated by the muscle belly.

Data-Driven Modeling of an Unsaturated Bentonite Buffer Model Test Under High Temperatures Using an Enhanced Axisymmetric Reproducing Kernel Particle Method

no code implementations24 Sep 2023 Jonghyuk Baek, Yanran Wang, Xiaolong He, Yu Lu, John S. McCartney, J. S. Chen

In deep geological repositories for high level nuclear waste with close canister spacings, bentonite buffers can experience temperatures higher than 100 {\deg}C. In this range of extreme temperatures, phenomenological constitutive laws face limitations in capturing the thermo-hydro-mechanical (THM) behavior of the bentonite, since the pre-defined functional constitutive laws often lack generality and flexibility to capture a wide range of complex coupling phenomena as well as the effects of stress state and path dependency.

A Multi-Resolution Physics-Informed Recurrent Neural Network: Formulation and Application to Musculoskeletal Systems

no code implementations26 May 2023 Karan Taneja, Xiaolong He, Qizhi He, J. S. Chen

This work presents a multi-resolution physics-informed recurrent neural network (MR PI-RNN), for simultaneous prediction of musculoskeletal (MSK) motion and parameter identification of the MSK systems.
