Optimization of ceramic strength using elastic gradients [PDF]
Acta Materialia, 2009 We present a new concept for strengthening ceamics by utilizing a graded structure with a low elastic modulus at both top and bottom surfaces sandwiching a high-modulus interior. Closed-form equations have been developed for stress analysis of simply supported graded sandwich beams subject to transverse center loads.

A gradient elasticity approach to the indentation size effect at very small depths
Journal of the Mechanical Behavior of Materials, 2011 Over the past two decades, the indentation size effect (ISE) has been studied extensively by several authors. A common point among all these studies has been the premise that during the indentation process sufficient plastic deformation is developed so ...

Journal of the Mechanical Behavior of Materials, 2014 Penalty functions, used in computational mechanics, can provide an interpretation of the effects of the spatial gradients in continuum mechanics. In particular, the use of mass penalties and the use of microinertia terms in gradient elasticity lead to ...

On the strain gradient bending deformations
Journal of the Mechanical Behavior of Materials, 2013 Bending deformations are reviewed in the context of strain gradient linear elasticity, considering the complete set of strain gradient components. It is well understood that conventional bending deformations depend on the collective uniaxial extension of

The ab-initio aided strain gradient elasticity theory
Fracture and Structural Integrity, 2019 When the width of cracked nanocomponents made of brittle or quasi-brittle materials is less than approximately , the size of the - dominance zone becomes smaller than and comparable to the fracture process zone ( ).

A note on the discrete approach for generalized continuum models
Journal of the Mechanical Behavior of Materials, 2014 Generalized continuum theories for materials and processes have been introduced in order to account in a phenomenological manner for microstructural effects.
