“…The literature consulted so far reveals that the problem of determination of elastic stresses and deformations in a cylinder made of monolithic material has been dealt with by several workers, but studies pertaining to creep deformations in cylinders, and also to FG composites, are rather scant. In the current authors' earlier work, based on creep behaviour of a uniform composite cylinder made of Al-SiCp and subjected to internal pressure, the role of size and content of the reinforcement (SiCp), and operating temperature has been investigated on stresses and strain rates in the cylinder [27]. The present work investigates steady-state creep in a thick-walled FG cylinder consisting of SiCp particles embedded in an Al matrix and subjected to high pressure and high temperature.…”

“…The present work investigates steady-state creep in a thick-walled FG cylinder consisting of SiCp particles embedded in an Al matrix and subjected to high pressure and high temperature. Unlike the authors' earlier work based on uniform composite cylinder [27], the present work considers FG cylinders in which the content of SiCp in the Al matrix has been assumed to vary linearly with the maximum amount at the inner radius and the minimum at the outer radius of cylinder. As a result of this, the creep parameters in the FG cylinders will be a function of radial distance, which would otherwise remain constant in uniform composite cylinders.…”

In the present study, a mathematical model has been developed to describe steadystate creep in an isotropic functionally graded composite cylinder. The cylinder is subjected to internal pressure and is made of functionally graded composite containing linearly varying silicon carbide particles in a matrix of pure aluminium. The cylinder is assumed to creep according to a threshold stress-based creep law having a stress exponent 5. The effect of employing a linear gradient in the distribution of reinforcement has been observed on the variation of creep stresses and creep rates in the composite cylinder. It is observed that the radial stress in the cylinder decreases throughout with the increase in reinforcement gradient, whereas the tangential, axial, and effective stresses increase significantly near the inner radius but show significant decrease towards the outer radius. The strain rates in the composite cylinder could be reduced significantly by tailoring the distribution of reinforcement while maintaining the same average amount of reinforcement. The distribution of strain rate becomes relatively uniform with increase in particle gradient.

“…The application of the finite-strain theory also permits the prediction of the time at which the cylinder will fail. The steady state creep in composite cylinder subjected to internal pressure was investigated by Singh and Gupta (2009). Singh and Gupta (2012) also investigated the thermal creep stresses of a functionally graded thick-walled cylinder subjected to internal pressure.…”

Purpose -Safety analysis has been done for thermal non-homogeneous thick-walled circular cylinder under internal and external pressure. The paper aims to discuss these issues. Design/methodology/approach -Transition theory based on the concept of generalized principal Lebesgue strain measure has been used which simplifies the constitutive equations by prescribing a priory the order of the measure of deformation and helps to achieve better agreement between the theoretical and experimental results. Findings -From the analysis, the paper can conclude that by introducing a suitably chosen temperature gradient, non-homogeneous compressible circular cylinder with internal and external pressure for non-linear measure is on the safer side of the design as compared to the cylinder without temperature because circumferential stresses are less for cylinder with temperature as compared to cylinder without temperature. Practical implications -Introduction of temperature gradient leads to the idea of "Stress Saving" and minimizing the possibility of fracture of cylinder. Originality/value -The paper shows that circumferential stresses are less for cylinder with temperature gradient as compared to cylinder at constant temperature, which leads to the idea of "Stress Saving" and minimizing the possibility of fracture of cylinder.
