Strain gradient thermopiezoelectric materials

Journal of Thermal Stresses, 2023
Results from the linear theory of thermopiezoelectricity are discussed in this article. A brief introduction to dielectric materials and the phenomenon of direct and inverse piezoelectricity is given. Then, a general theory of thermopiezoelectricity for strain gradient materials is given, where the second gradient of the displacement field and electric

Strain gradient plasticity in gradient structured metals

Journal of the Mechanics and Physics of Solids, 2020
Abstract Structural gradients in metallic materials can give rise to substantial extra strengths compared to their non-gradient counterparts. This strengthening effect originates from the plastic strain gradients arising in plastically deformed gradient structures.

Mechanism-Based Strain Gradient Crystal Plasticity

MRS Proceedings, 2004
AbstractTo model size dependent plastic deformation at micron and submicron length scales the theory of mechanism-based strain gradient plasticity (MSG) was developed. The MSG approach incorporates the concept of geometrically necessary dislocations into continuum plastic constitutive laws via Taylor hardening relation. This concept is extended here to

Strain gradient nonlocal Biot poromechanics

International Journal of Engineering Science, 2020
Abstract Experimental observation demonstrates that both negative and positive dispersion relations are possible for porous media, which classical Biot theory fails to predict and interpret. The present paper establishes a higher-order strain gradient nonlocal poroelasticity considering both the size effects and heterogeneity structure effects to ...
