Size effects (SEs) exist in many domains, and are caused by changes in the values of
parameters of materials, structures, or systems individually or collectively known as size …

Over the last three decades, a number of researchers have used the gradient-enhanced
plasticity theory to model the microstructural material behavior, which is not able to be …

A standard experimental method for determining the intrinsic material length scale of
modified couple stress theory is proposed based on a non-contact laser Doppler vibration …

Deformation mechanism-based constitutive modeling can serve as a flexible tool to optimize
the microstructure of hetero-structured metals for achieving better mechanical performance …

The size-dependent elasticity of a series of nickel cantilever microbeams was investigated
experimentally for the first time. The experimental results revealed that the dimensionless …

This paper investigates the three-dimensional motion characteristics of perfect and imperfect
Timoshenko microbeams under mechanical and thermal forces; the mechanical properties …

The size-dependent nonlinear oscillation characteristics of a functionally graded microplate
is investigated numerically, in which all the displacements, ie in-plane as well as out-of …

Systematical microstructure characterization, mechanical testing and constitutive modeling
were carried out to quantify the effects of residual stress and grain refinement on tensile …

Both torsion and tensile tests are performed on polycrystalline copper wires with diameters
in the range 20–50μm. A significant size effect in both the initial yielding and the plastic flow …

The aim of this paper is to develop a new nonlinear theoretical model for cantilevered
microbeams and to explore the nonlinear dynamics based on the modified couple stress …
