Implicit Sub-stepping Scheme for Critical State Soil Models
Hoang Giang Bui, Jelena Ninic, Günther Meschke
The stress integration of critical soil model is usually based on implicit Euler algorithm, where the stress predictor is corrected by employing a return mapping algorithm. In the…
Asymptotically accurate and geometric locking-free finite element implementation of a refined shell theory
Khanh Chau Le, Hoang-Giang Bui
Accurate finite element analysis of refined shell theories is crucial but often hindered by membrane and shear locking effects. While various element-based locking-free techniques…
Asymptotically accurate and locking-free finite element implementation of first order shear deformation theory for plates
Khanh Chau Le, Hoang Giang Bui
A formulation of the asymptotically exact first-order shear deformation theory for linear-elastic homogeneous plates in the rescaled coordinates and rotation angles is considered.…
Elasto-plastic large deformation analysis of multi-patch thin shells by isogeometric approach
Giang Huynh, Xiaoying Zhuang, Hoang-Giang Bui +2
This paper studies elasto-plastic large deformation behavior of thin shell structures using the isogeometric computational approach with the main focus on the efficiency in modelli…
