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…
A new one point quadrature rule over arbitrary star convex polygon/polyhedron
Sundararajan Natarajan, Amrita Francis, Elena Atroshchenko +1
The Linear Smoothing (LS) scheme \cite{francisa.ortiz-bernardin2017} ameliorates linear and quadratic approximations over convex polytopes by employing a three-point integration sc…
Linear smoothed extended finite element method
M Surendran, S Natarajan, SPA Bordas +1
The extended finite element method (XFEM) was introduced in 1999 to treat problems involving discontinuities with no or minimal remeshing through appropriate enrichment functions.…
