Elbow pipe components are frequently subjected to complicated thermo-mechanical load
combinations cyclically in nuclear engineering, facing failures related to cyclic plastic …

Ratcheting effect refers to the cyclic accumulation of plastic strain under alternating load, is
one of the reasons leading to the failure of mechanical structures. The concept of structural …

The traditional approach to structural lightweight optimization design, which is based on the
elastic limit rule, often results in a structure that exhibits either weight redundancy or strength …

Abstract Printed Circuit Heat Exchangers (PCHEs) is a kind of compact plate heat exchanger
with a lot of fine channels in a solid block, called PCHE core. It can withstand high …

This paper has investigated cyclic plasticity of a reactor pressure vessel (RPV) nozzle
subjected to cyclic thermo-mechanical loads thoroughly: cyclic thermal loads, cyclic bending …

The conditions required for the ratcheting of a structure due to thermal and load cycling are
typically calculated assuming a constant Young's modulus throughout the cycle. We show …

As the main component of the crewed spacecraft, the space capsule used for future space
missions, especially for the deep-space explorations, must be safe, lightweight, and …

This research studies the effect of wall thinning on generated shakedown (SD) interaction
diagrams of pressurized low-carbon steel 90-degree (90-Deg) back-to-back (B2B) bends …

According to the extended Melan's static theorem, theoretical and numerical aspects of the
stress compensation method (SCM) are presented to perform shakedown analysis of elastic …

Mechanical components are often subjected to time-varied loading during their service. One
of the key objectives for designing these parts is to reduce the weight while maintaining the …
