Recent Developments in CAD/analysis Integration
H. Lian, S. P. A. Bordas, R. Sevilla +1
For linear elastic problems, it is well-known that mesh generation dominates the total analysis time. Different types of methods have been proposed to directly or indirectly allevi…
NURBS-based finite element analysis of functionally graded plates: static bending, vibration, buckling and flutter
Navid Valizadeh, Sundararajan Natarajan, Octavio A Gonzalez-Estrada +3
In this paper, a non-uniform rational B-spline based iso-geometric finite element method is used to study the static and dynamic characteristics of functionally graded material (FG…
A hybrid extended finite element/level set method for modeling equilibrium shapes of nano-inhomogeneities
Xujun Zhao, Stéphane P. A. Bordas, Jianmin Qu
Interfacial energy plays an important role in equilibrium morphologies of nanosized microstructures of solid materials due to the high interface-to-volume ratio, and can no longer…
Supersonic flutter analysis of thin cracked functionally graded material plates
S Natarajan, M Ganapathi, S Bordas
In this paper, the flutter behaviour of simply supported square functionally graded material plates immersed in a supersonic flow is studied. An enriched 4-noded quadrilateral elem…
Efficient recovery-based error estimation for the smoothed finite element method for smooth and singular linear elasticity
Octavio A. González-Estrada, Sundararajan Natarajan, Juan José Ródenas +2
An error control technique aimed to assess the quality of smoothed finite element approximations is presented in this paper. Finite element techniques based on strain smoothing app…
