A Formulation for the Characteristic Lengths FCC in First Gradient Elasticity Via Sutton-Chen Potential, M.Sc. Thesis Sharif University of Technology ; Mohammadi Shoja, Hossein (Supervisor)
Abstract
The usual continuum theories are inadequate in predicting the mechanical behavior of solids in presence of small defects and stress concentrators; it is well known that such continuum methods are unable to detect the change of the size of the inhomogeneities and defects. For these reasons various augmented continuum theories and strain gradient theories have been proposed in the literature. The major difficulty in implication of these theories lies in the lack of information about the additional material constants. For fcc metals, for calculation of the associated characteristic lengths which arise in first strain gradient theory, an ...
