The main objective of this paper is to determine the stresses and displacements in radially graded multilayered spherical bodies made from incompressible functionally graded materials. The material properties are arbitrary functions of the radial coordinate. The body is subjected to constant pressure and a temperature field, which is an arbitrary function of the radial coordinate. An analytical method is presented to tackle these problems then compared to solutions coming from finite element simulations.
Ez a tanulmány a kompozitok általános tulajdonságairól ad egy rövid áttekintést. A lineáris rugalmasságtan keretein belül sor kerül az anyagegyenletek ismertetésére, külön kiemelve az általánosan ortotrop anyagi viselkedést. Ezek után egy lemez alkatrész végeselemes vizsgálata demonstrálja egy epoxy mátrixú grafit erősítőszálakat tartalmazó kompozit adta tömegcsökkentési lehetőséget egy általános acélhoz képest.
