Temporal Effects of Thermal Stresses on Solid Dielectric Materials under Diverse Voltage Conditions

open access: yesPakistan Journal of Engineering & Technology, 2022
Dielectric materials are an essential part of the power system and their healthy condition is necessary for the stable system operation. Thermal stresses occurring due to faults have adverse effects on the life of insulating materials.

Impact of Heat Transfer on Transient Stress Fields in Power Plant Boiler Components

open access: yesEnergies, 2021
In boilers operating in modern power plants, thick-walled elements of complex shapes, such as valves, superheater headers, T-pipes, Y-pipes, four-way pipes, and elbows, are especially prone to fatigue processes.

Effect of Residual Thermal Stresses in Curing Process on the Deformation of Flat and Cylindrical Composite Laminates [PDF]

open access: yesعلوم و تکنولوژی پلیمر, 2009
Unsymmetrical composite laminates deform from the flat state in curing process. According to the "lamination theory" the cured shape of unsymmetrical laminates should always be saddle-like, while considering parameters like specimen lengths and cure ...
