Thermoelectroelastic response of a piezoelectric cylinder with D∞ symmetry under axisymmetric mechanical and thermal loading

Mechanical Engineering Journal, 2017
Carbon-neutral and biodegradable materials such as wood and poly-L-lactic acid play an important role in reducing environmental loads. Therefore, this study theoretically analyzed the thermoelectroelastic problem for a solid cylinder with D∞ symmetry ...

Electroelastic field in a piezoelectric solid cylinder with D∞ symmetry subjected to transverse mechanical load

Mechanical Engineering Journal, 2017
For the safe operation of devices comprised of bodies with D∞ symmetry, the electroelastic field in a solid cylinder subjected to a non-axisymmetric surface load of radial and circumferential stresses was investigated.

Chemiluminescent wood

Carbohydrate Polymers
Wood materials incorporating new properties are of great interest, especially for advanced applications such as sustainable optics and photonics. In this work we describe a wood functionalization approach, comprising the incorporation of artificial chemiluminescent systems (phenyl oxalate ester‑hydrogen peroxide-fluorophore, and luminol-ferricyanide ...

Simulating Strength Behaviors of Corner Joints of Wood Constructions by Using Finite Element Method

Drvna Industrija, 2016
Using finite element method (FEM) has become wide spread in the field of wood mechanics for analyzing difficult problems instead of conventional methods. The objective of this study is to determine the strength properties of wood corner joints using FEM.

Une statue d’Epona en tôle de bronze sur modèle en bois à Saint-Valérien (Yonne)

Revue Archéologique de l’Est, 2013
Partial exploration (1,7 hectares) of a large village close to Sens has revealed enclosures and wooden constructions, some containing forges, close to a large galleried courtyard. The stages of development during the 1st and 2nd centuries were discerned,

Un exemple de charpente à double croupe du début du xiiie s. : la porterie du prieuré de Courtozé à Azé (Loir-et-Cher)

Revue Archéologique du Centre de la France
Located in an isolated valley near Vendôme, the former priory of Courtozé in Azé (Loir-et-Cher) preserves a medieval building that was once the gatehouse, associated with fragments of an enclosure wall.
