In this article, vibration characteristics and the parametric instability of functionally graded material (FGM) plates with cyclic loading in a hygrothermal field are discussed. The plate element is modeled in a finite element by applying the third-order shear deformation hypothesis. The mathematical formulation of the FGM plate is made with two material constituents by applying the power rule ...

This study, it is aimed to determine the adhesion strength of varnish layers applied surface fresh and naturally aged wood materials. For this purpose, oak (Quercus Petrea L.), chestnut (Castanea sativa M.) Scots pine (Pinus sylvestris L.) materials were used for each species, age period, section direction type. A total 360 test samples prepared polyurethane, acrylic water-based varnishes their...

Tremendous opportunities exist for biomaterials in biomedical applications. Microalgae, as a kind of natural resources, have been recently used novel biological materials, and attracted great deal interest this field. The unique morphological characteristics easily functionalized surfaces microalgae allow the attachment diagnostic or therapeutic agents on their surface, making them promising ca...
