ICD: A methodology for real time onset detection of overlapped acoustic emission waves
TL;DR: ICD is introduced to enhance detectability, reliability, and accuracy of a conventional system and source localization results from laboratory testing confidently display the scientific applicability of the proposed system.
Derivation of crack bridging stresses in engineered cementitious composites under combined opening and shear displacements
TL;DR: In this article, a micromechanics based theoretical model is proposed to describe the shear transfer mechanism on the crack surface due to fiber bridging effect, and the model focuses on flexible fibers and both the normal stress along the crack opening direction and the Shear stress transferred across the crack surfaces are derived under the coupled effect of crack opening displacement (COD) and shear sliding.
Micromechanical modeling of crack-bridging relations of hybrid-fiber Strain-Hardening Cementitious Composites considering interaction between different fibers
TL;DR: In this paper, the crack-bridging relations of hybrid polyvinyl alcohol (PVA) and steel fibers were theoretically modeled and compared to the test results in terms of the tensile strength and the corresponding crack opening.

TL;DR: In this article, the effects of key composition parameters including the length of polyethylene (PE) fibers and the maximum size of sea-sand (1.18 mm, 2.36 mm, and 4.75 mm) on the mechanical performance of SS-ECC were investigated.
Freeze-Thaw Durability of Microwave Cured Air-Entrained Concrete
TL;DR: In this article, the freeze-thaw resistance of microwave cured air-entrained concrete is measured, and compared to that of normal curing under normal curing, their compressive strength at 14 days and air-void characteristics are also measured and compared.
