THERMAL STRESSES ANALYSIS IN AN ISOTROPIC MATERIAL DISC SUBJECTED TO
THERMAL LOAD AND DENSITY WITH RIGID INCLUSION
The objective of this paper is to present the study thermal stresses in
an isotropic material disc with rigid inclusion and subjected to
mechanical load and density parameter by using transition theory. The
transition theory includes classical macroscopic solving problems in
plasticity, creep relaxation, and semi-empirical yield conditions. It
has been observed that the radial stress has a maximum value at the
internal surface of the disc made of compressible material (i.e. copper)
as compared to the disc made of incompressible material (i.e. rubber).
With the introduction of thermal condition, density parameter and load,
the values of radial and circumferential stress increase of the internal
surface of compressible/ incompressible materials. The displacement
component increased at the outer surface of the disc made of
compressible /incompressible materials and fully plastic stage. Results
have been discussed numerical and depicted graphically.
