In this paper the vibration of a spinning cylindrical shell made of functional graded material is investigated. After a brief introduction of FG materials, by employing higher order theory for shell deformation, constitutive relationships are derived. Next, governing differential equation of spinning cylindrical shell is obtained through utilizing energy method and Hamilton’s principle. Making ...

this research develops thermo-elastic analysis of a functionally graded cylinder under thermo-mechanical loadings. heat conduction equation in cylindrical coordinate system is solved. thermal conductivity coefficient is graded along the radial direction. by considering a symmetric distribution of temperature, loading and boundary conditions, strain-displacement and stress-strain relations can b...

For the production of nanoplates from layered crystals by liquid-phase shear exfoliation, patent-protected technologies and equipment have been developed. The main difference between proposed known ones is that exfoliation process possible only shearing in continuous operation. Particular interest can be explained following advantages this technology relation to others: chemical reagents are us...

The response of total creatine kinase (CK) and the creatine kinase isoenzyme (CK MB) was studied in 22 male post-infarction patients (three to six months after myocardial infarction) after a functional graded exercise test, before entering a rehabilitation programme. Eleven subjects (group A) completed the test without developing significant electrocardiographic abnormalities. Eleven subjects (...

Abstract We consider the problem of determining, within an elastic isotropic nanoplate in bending, possible presence inclusion made different material. Under suitable a priori assumptions on unknown inclusion, we provide quantitative upper and lower estimates for area defect terms works exerted by boundary data when is present it absent.
