The assessment of cracks in civil infrastructures commonly relies on visual inspections
carried out at night, resulting in limited inspection time and an increased risk of crack …

The finite element method (FEM) based on the Gurson–Tvergaard–Needleman (GTN)
model was used to investigate the ductile crack growth behaviors at different weld joint …

Abstract The Hybrid Metal Extrusion & Bonding (HYB) process is a patented solid state
joining method for metals which utilizes filler material additions to consolidate the weld. In …

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 …

A mesh refinement procedure designed for Digital Image Correlation analyses of cracked
media is proposed, based on the pixel color for an artificial case, and the crack opening …

Single-edge notched tension (SENT) testing has gained attention for the characterization of
crack growth resistance in scenarios of low crack tip constraint conditions. One challenge of …

摘要使用数字图像相关(DIC) 方法测量平滑, 准确的裂纹尖端位移场和应变场是学术界难题之一.
目前常用的方法为基于子区的局部DIC 方法, 但其子区跨裂纹计算的结果无意义 …

The experimental evaluation of fracture toughness of linepipe steels is increasingly
performed through Single Edge Notched Tensile (SENT) testing. The notch constraint in …

This manuscript presents a non-contact approach to measure the J-integral resistance (JR)
curve for side-grooved specimens using data measured solely from the digital image …

The results of visual inspection of welds depend on the visual ability of inspector. With the
optical macro-photogrammetric low-cost procedure proposed in this paper only a digital …
