Current Research Interests
Various problems in the field of theoretical and applied mechanics, particularly,
Nano/micro-scale modeling of defects in ultra-small objects and thin films via
atomistic approaches, augmented continuum theories, and micromechanical
considerations; capturing the surface and size effects. Ab initio calculations of
the characteristic lengths of the crystalline materials in first and second strain
gradient elasticity. Micromechanical based theories for the prediction of the overall
behavior of elastic solids with high concentration of multi-phase particles as well
as calculations of the effective moduli of nano-composites based on higher order
theories. Employment of the combined analytical and first principles calculations
based on density functional theory to study the mechanical behavior of carbon
nano-tubes. Determination of the surface energy, surface stress, and surface elastic
constants of ideal and reconstructed surfaces via combined first principles and
One of the special interests is the basic research in the development of theorems
associated with the multi-inclusions, multi-inhomogeneities (with anisotropic
constituents), and impotent eigenstrains which are of fundamental importance in the
study of micromechanics of defects in solids. These theorems are concerned with the
prediction of the exact nature of the elastic fields within the
constituent phases of a
multi-inhomogeneous inclusion and its surrounding matrix under general far-field
loading. Introduction of such innovative viewpoints of equivalent inclusion method
(EIM) as the spectral EIM for rigorous and exact determination of the elastic fields;
introduction of the notion of eigenbody-force fields needed for a sound basis of the
dynamic EIM (DEIM). Moreover, extension of the concept of eigenstrain to the
atomistic level in the atomistic study of thin-films; relation between eigenstrain and
potential function suitable for accounting for the short and long range inter-atomic
interactions. Development of a unified approach for determination of the closed-form
expressions for modes I, II and III stress intensity factors at the tips of lamellar
inhomogeneities under a remote applied polynomial loading based on Eshelby’s EIM.
In addition to the analytical treatments, development of innovative
computational methods such as gradient reproducing kernel particle method (GRKPM)
and generalized RKPM are of interest; employment of GRKPM to such highly
nonlinear partial differential equations as Burger’s equation and Buckley-Leverett’s
equation which are characterized by exhibition of steep moving fronts.
