Study of Manufacturing Process of Holes in Aeroengine Heat Shield
International Journal of Aerospace Engineering, Volume 2019, Issue 1, 2019., 2019 The nickel‐based superalloy GH3128 with high plasticity, high long‐lasting creep strength, good resistance to oxidation and stamping, and good welding performance is widely used in aircraft engine heat shields. The many holes that need to be machined on the heat shield are not only small in diameter but also dense, and GH3128 as a typical hard‐to ...

Mathematical Problems in Engineering, Volume 2018, Issue 1, 2018., 2018 Mean stress effect plays an important role in fatigue life prediction, and it is discovered that maximum stress has nonnegligible influence on mean stress effect. Therefore, a modified Walker model is proposed to account for mean stress effect on fatigue life of aeroengine disks, which contains the influence of stress ratio and maximum stress on mean ...

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Nickel‐based superalloys (Ni‐based superalloys) have attracted extensive attention in laser additive manufacturing (LAM) due to their capability to directly fabricate complex and high‐performance structural components. However, the rapid melting and solidification inherent to LAM result in intense thermal cycling, which induces high residual ...

Reliability Analysis on Structures Based on a Modified Iterative Response Surface Method
Mathematical Problems in Engineering, Volume 2018, Issue 1, 2018., 2018 In order to improve the computational accuracy and efficiency of response surface method for reliability analysis on structures, a modified iterative response surface method (called as NDIRSM) is proposed. Firstly, a new starting center point, which is closer to design point, is calculated out as the starting center point instead of the point at mean ...
