TLDR
In this paper, Cimento revisited some variational principles for the fundamental equations of a regular region of piezoelectric, thermopiez-olectric and hygrothermopiezoellectric materials in the elastic range.Abstract:
In this paper some variational principles are revisited for the fundamental equations of a regular region of piezoelectric, thermopiezoelectric, and hygrothermopiezoelectric (but non-stochastic, non-local, and non-relativistic) materials in the elastic range. Certain oversights, and especially, those involving the so-called Hu-Washizu variational principle of piezoelectricity that was first formulated in a paper (“Variational Principles in Piezoelectricity,” Lettere Al Nuovo Cimento, vol. 7, 449–454, 1973) are clarified within the “ISI-Web of Science” publications in the open literature. Similar variational principles of piezoelectricity are cited.read more

About heat waves
TL;DR: In this article, the Belgian Pilots' Guild raised the question of what effect exposure to radar radiation might have on the human body and reported that in 25 years of experience with radar, there were no known incidents of pilots being affected by radar waves.

Variational Principles in Mechanics
TL;DR: In this article, the authors define the principle of virtual work, which is a departure from other minimizing principles in that it incorporated stationarity and local stationarity in its formulation, and it is used to characterize static equilibrium through requiring that the work done by the external forces during a small displacement from equilibrium should vanish.

Review: A review of active structural control: challenges for engineering informatics
TL;DR: An active structure is an engineering structure containing sensors and actuators that, when active, modify the response of the structure to its environment as discussed by the authors, and it is a type of structural control that can be used in extreme environments (space, undersea, polar), contaminated contexts (nuclear, chemical, biological).

The elastic dielectric.
TL;DR: Slepian used an operational "definition" of stress and concluded that the compensating mechanical forces which must be introduced operationally are not derivable from a tensor.

Poisson transduction of noise stimuli: Some results of a computer simulation
Paul N. Schacknow,David H. Raab +1 more
TL;DR: A Monte‐Carlo procedure was used to simulate noise‐intensity discrimination and poisson transduction (with compression) was modeled in both ’’energy‐summation’s’ and ‘’neural‐summies’ versions’, confirming the existence of these two mechanisms.
New principles of work and energy as well as power and energy rate for continuum field theories
Dai,Tian-min(戴天民) +1 more
TL;DR: In this article, the authors presented new principles of work and energy as well as power and energy rate with cross terms for polar and nonlocal polar continuum field theories and corrected the incompleteness of all existing corresponding principles and laws without cross terms in literatures of generalized Piola' s theorems.
