Polytopal composite finite elements for modeling concrete fracture based on nonlocal damage models
Hai D. Huynh, S. Natarajan, H. Nguyen-Xuan +1
The paper presents an assumed strain formulation over polygonal meshes to accurately evaluate the strain fields in nonlocal damage models. An assume strained technique based on the…
Adaptive phase field modelling of crack propagation in orthotropic functionally graded materials
Hirshikesh, Emilio Martínez-Pañeda, Sundararajan Natarajan
In this work, we extend the recently proposed adaptive phase field method to model fracture in orthotropic functionally graded materials (FGMs). A recovery type error indicator com…
Continuum modelling of stress diffusion interactions in an elastoplastic medium in the presence of geometric discontinuity
Rupesh Kumar Mahendran, Hirshikesh, Ratna Kumar Annabattula +1
Chemo-mechanical coupled systems have been a subject of interest for many decades now. Previous attempts to solve such models have mainly focused on elastic materials without takin…
Isogeometric analysis of thin Reissner-Mindlin plates and shells: locking phenomena and B-bar method
Qingyuan Hu, Yang Xia, Sundararajan Natarajan +3
We propose a local type of B-bar formulation, addressing locking in degenerated Reissner-Mindlin plate and shell formulations in the context of isogeometric analysis. Parasitic str…
