| Abstract |
We construct a mathematical model describing thermomechanical
interaction between composite structure elements (isotropic
particles of the matrix and anisotropic short fibers) and the
macroscopically isotropic elastic medium with desired thermoelastic
characteristics. At the first stage of this model, the
self-consistency method is used to obtain relations determining the
elasticity moduli of the composite, and at the second stage, the
model permits determining its linear thermal expansion coefficient.
The dual variational statement of the linear thermoelasticity
problem in an inhomogeneous solid permits obtaining two-sided
estimates for the bulk elasticity modulus, shear modulus, and
linear thermal expansion coefficient of the composite under study.
The calculated dependencies presented in the paper permit
predicting the thermoelastic characteristics of a composite
reinforced by anisotropic short fibers (including those in the form
of nanostructure elements). |
