Powder metallurgy (PM) Ni-based superalloys are widely used for aeroengine turbine disc
applications due to their excellent mechanical properties and good corrosion resistance at …

In recent years, digital image correlation has been widely used in the analysis of crack
problems. This review will examine digital image correlation, as a full‐field measurement …

疲劳是机械结构最普遍的失效模式之一. 自1854 年第一次提出“Fatigue”(疲劳) 概念以来,
相关研究已有160 余年的历程, 逐步形成了以疲劳研究为基础的机械结构强度理论与技术 …

The full-field digital image correlation (DIC) technique was used to identify crack initiation
and early crack growth on irregular, corroded surfaces from offshore mooring chain. Finite …

The advent of digital image and volume correlation has attracted wide use in fracture
mechanics. The full‐field nature of digital image and volume correlation allows for the …

The girth-weld joint of a pipeline can be divided into three parts: base metal, heat affected
zone, and weld metal. This study investigates the local mechanical properties of X80 and …

Fatigue crack growth retardation of AZ31 alloy under a single tensile overload was
investigated by 3D synchrotron radiation, 2D in-situ SEM and digital image correlation …

In this paper, in-situ SEM images with both low and high resolution near fusion line of a Cr-
Ni-Mo-V steel welded joint were taken during interrupted monotonic tensile tests, with which …

In the past three decades, quantitative characterization of cracks attracted much attention
with the development of digital image correlation (DIC), especially for estimation of crack tip …

Crack-tip strain localization and accumulation has long been recognized while the
mechanics and physics of fatigue are yet to be understood for complicated cracking modes …
