Fatigue crack behaviour: comparing three-point bend test and wedge splitting test data on vibrated concrete using Paris' law [PDF]

Fracture and Structural Integrity, 2017
The fatigue behaviour of concrete has become more important for the design of constructions due to the desire to build slimmer structures, which are more sensitive to fatigue loading.

Safety assessment of the process Starlinger viscotec deCON used to recycle post-consumer PET into food contact materials. [PDF]

EFSA J
Abstract The EFSA Panel on Food Contact Materials (FCM) assessed the safety of the recycling process Starlinger viscotec deCON (EU register number RECYC339). The input is washed and dried poly(ethylene terephthalate) (PET) flakes originating from collected post‐consumer PET containers, with no more than 5% PET from non‐food consumer applications.

Safety assessment of the process Starlinger viscotec viscoZERO PET used to recycle post-consumer PET into food contact materials. [PDF]

EFSA J
Abstract The EFSA Panel on Food Contact Materials (FCM) assessed the safety of the recycling process Starlinger viscotec viscoZERO PET (EU register number RECYC340). The input is hot washed and dried poly(ethylene terephthalate) (PET) flakes mainly originating from collected post‐consumer PET containers, with no more than 5% PET from non‐food consumer ...

Applicability of CMOD to Obtain the Actual Fracture Toughness of Rightly-Cracked Fibrous Concrete Beams

Buildings, 2023
Unfortunately, most of the previous work studying the fracture toughness of fibrous composites has deliberately ignored bridging the fiber onto the pre-crack/notch surfaces by creating such a crack as a through-thickness crack (TTC).

Research on the Evolution of Shield Segment Cracks Based on Acoustic Emission and CMOD

Materials, 2022
In order to explore the cracking law and failure characteristics of segments, a model test of shield segment cracking was conducted. The microscopic and macroscopic crack evolution process of the segment is studied by using acoustic emission detection technology and crack opening displacement (CMOD).

Numerical simulation and experimental verification of CMOD in SENT specimen: Application on FCGR of welded tool steel [PDF]

Acta Metallurgica Sinica (English Letters), 2013
Single-edged notched tension (SENT) specimen is used to study the fatigue crack growth rate (FCGR) behavior of AISI 50100 steel using MTS 810. Calibration tests are run to get plots of crack mouth opening displacement (CMOD) vs. load and CMOD vs. crack length-to-width ratio with the known crack lengths.
