Phase-Field Modeling of Domain Structure Energetics and Evolution in Ferroelectric Thin Films
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A computational model developed based on the phase-field approach is used to model domain structures in ferroelectric thin films and to quantify the effects of strain and applied electric field ...
On the Path-Dependence of the J-Integral Near a Stationary Crack in an Elastic-Plastic Material
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The path-dependence of the J-integral is investigated numerically via the finite-element method, for a range of loadings, Poisson’s ratios, and hardening exponents within the context of J2-flow ...
Electrostatic Forces and Stored Energy for Deformable Dielectric Materials
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An isothermal energy balance is formulated for a system consisting of deformable dielectric bodies, electrodes, and the surrounding space. The formulation in this paper is obtained in the ...
Erratum: “Electrostatic Forces and Stored Energy for Deformable Dielectric Materials” [Journal of Applied Mechanics, 2005, 72(4), pp. 581–590]
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this Erratum we point out and correct an omission of an important term in Eq. (8) of our original paper. This equation was a statement of the conservation of angular momentum and we ...
A Note on the Path-Dependence of the J-Integral Near a Stationary Crack in an Elastic-Plastic Material With Finite Deformation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this technical brief, we compute the J-integral near a crack-tip in an elastic-perfectly-plastic material. Finite deformation is accounted for, and the apparent discrepancies between the prior ...
