...M. Jabbari; H. Dehbani; M. R. Eslami In this paper, the classic coupled thermoelasticity model of hollow and solid cylinders under radial-symmetric loading condition ( r , t ) is considered. A full analytical method is used, and an exact unique solution of the classic coupled equations is presented...

...Z. H. Ning; R. H. Liu; S. Q. Huang; X. S. Lu Craze cracking and clad disbonding typically occur in cladding due to thermomechanical cycling and high property mismatch between dissimilar materials in a coke drum. The thermoelasticity problem in a coke drum with cladding is assumed quasi-static...

... direction. Temperature distribution is symmetric and transient. The thermal boundary conditions may include conduction, flux, and convection for inside or outside of a hollow cylinder. The thermoelasticity equation is transient, including the moving heat source. The heat conduction and Navier equations...

...A. E. Segall; D. Engels; A. Hirsh Thermoelastic states as they pertain to thermal-shock are difficult to determine since the underlying boundary conditions must be known or measured. For direct problems where the boundary conditions such as temperature or flux, are known a priori, the procedure...

The elastic hoop stress concentration factor (SCF) traditionally is defined as the ratio of the maximum first principal stress over...

..., the analysis should always be restricted to the time interval used to describe the polynomial to avoid the risk of it going astray. With the thermoelastic stress state approximated for an arbitrary thermal shock, the transient mode-I stress intensity factors, K I were then calculated using...

Approximate rules for direct and inverse Laplace transformations were then used to modify the resulting Volterra equation to an algebraically solvable and relatively simple form. The desired thermoelastic stress distributions were...

...A. E. Segall A common threat to thick-walled vessels and pipes is thermal shock from operational steady state or transient thermoelastic stresses. As such, boundary conditions must be known or determined in order to reveal the underlying thermal state. For direct problems where all boundary...

The ensuing series representation of the temperature distribution as a function of time and radial position was then used to derive new relationships for the transient thermoelastic stress-states. Excellent agreement was seen between...
