A meshless method in the non-local constitutive damage models
Procedia Structural Integrity, 2016 AbstractThe radial point interpolation method (RPIM), as an advanced discretization approach, is used to analyze concrete structures assuming a non-linear continuum damage model. The theoretical basis of the material, damage characteristics and the computational procedure are presented.

A Local Meshless Method for Approximating 3D Wind Fields
Journal of Applied Meteorology and Climatology, 2016 AbstractAn efficient, mesh-free numerical method has been developed for creating 3D wind fields using data from meteorological towers. Node points are placed within a region of interest, generally based upon topological features. Since meshless methods do not require connective mesh generation, storage is greatly reduced, permitting implementation of ...

Meshless Local Petrov-Galerkin Method for Plane Piezoelectricity
Computers, Materials & Continua, 2006 Piezoelectric materials have wide range engineering applications in smart structures and devices. They have usually anisotropic properties. Except this complication electric and mechanical fields are coupled each other and the governing equations are much more complex than that in the classical elasticity. Thus, efficient computational methods to solve
