Shape Sensitivity Analysis of History‐Dependent Materials for Dynamic Structures
Proceedings in Applied Mathematics and Mechanics, Volume 25, Issue 1, March 2025.ABSTRACT This work presents a sensitivity analysis of inelastic material behavior within dynamic structures. The primary focus is on using the direct differentiation method to derive sensitivity matrices for displacement, velocity, acceleration, and history variables. These methods are validated through a detailed academic example.

A locking-free quadratic nurbs-based isogeometric formulation for plates analysis
Ho Chi Minh City Open University Journal of Science - Engineering and Technology, 2012 A new Reissner-Mindlin plate formulation based on a quadratic NURBS-based isogeometric is presented. In order to avoid the transverse shear locking and to improve the accuracy of the present formulation, the quadratic NURBS-based isogeometric is ...
