    Investigating Fracture Behavior in Titanium Aluminides: Surface Roughness as an Indicator of Fracture Mechanisms in Ti-48Al-2Cr-2Nb Alloys by Alessia Serena Perna, Lorenzo Savio, Michele Coppola, Fabio Scherillo

    Published 2025-01-01
    “…A novel method, employing confocal microscopy acquisitions, is proposed to correlate surface roughness parameters with the causes of failure, offering new insights into the fracture mechanisms of titanium aluminides. The results reveal significant differences in roughness values between the propagation and fracture zones for all the temperatures and microstructure tested. …”

    The effect of shielding gas composition on the toughness and crack growth parameters of AlMg4,5Mn weld metals by Prokić-Cvetković R., Kastelec-Macura S., Milosavljević A., Popović O., Burzić M.

    Published 2010-01-01
    “…Also, the weld metal toughness was estimated, using the instrumental Charpy impact testing system, followed by estimating the crack initiation energy, crack growth energy and the fracture mechanics parameters. The goal was to establish the effects of shielding atmosphere composition on the mechanical properties and fracture mechanics parameters of weld metal.…”

    The Size Effect and Microstructure Changes of Granite after Heat Treatment by Zhongping Guo, Jian Li, Yongqi Song, Chengqian He, Fuyu Zhang

    Published 2021-01-01
    “…The fracture toughness of two kinds of rocks was tested by fracture tests, and the results were analyzed by a nonlinear fracture mechanics model (SEL). At the same time, in order to understand the influence of high temperature on the mineral composition and microstructure of granite, XRD, optical microscope, and SEM were used to observe the mineral composition, microcracks, and fracture morphology of granite. …”

    Residual strength evaluation by DBEM for a cracked lap joint by R. Citarella

    Published 2016-02-01
    “…The model adopted for Stress Intensity Factors (SIFs) evaluation is based on the use of the Dual Boundary Element Method (DBEM) within the theoretical frame of Linear Elastic Fracture Mechanics (LEFM). The value of failure load was available from experiments, allowing a comparison with numerical results and consequent validation of the described procedure.…”
