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

Fracture in strain gradient elasticity

Metals and Materials, 1998
Recent experiments have shown that the microscale material behavior is very different from that of bulk materials, and displays strong size effects when the characteristic length associated with the deformation is on the order of microns. Conventional continuum theories, however, can not predict this size dependence because they do not have an ...

On a strain gradient theory of thermoviscoelasticity

Mechanics Research Communications, 2013
This paper is concerned with a strain gradient theory of thermoviscoelasticity in which the time derivatives of the strain tensors are included in the set of independent constitutive variables. The theory is motivated by the recent interest in the study of gradient theories.

The development of strain-rate gradients

Acta Metallurgica, 1979
Abstract The development of nonuniformities in tensile deformation and its dependence on material parameters and external conditions have been reanalyzed. It is found that the major influence of strain rate on neck growth is usually through its effect on the rate of strain hardening, rather than on the flow stress itself.

Formulations of Strain Gradient Plasticity

2011
In the literature, different proposals for a strain gradient plasticity theory exist. So there is still a debate on the formulation of strain gradient plasticity models used for predicting size effects in the plastic deformation of materials. Three such formulations from the literature are discussed in this work.

A strain gradient theory of plasticity

International Journal of Solids and Structures, 1970
Abstract A theory which includes first and second strain gradients is proposed as a model for plastic deformations. Heuristic arguments for including the gradients are also given. The main goal is to develop a logical framework in which behavior on a small scale can interact with the response on a larger one.
