Investigating Nonlinear Fatigue Damage Evolution of SBS-Modified Asphalt Mixtures with Physical Gel Structure

open access: yesGels
Styrene-butadiene-styrene (SBS) modifier can enhance the resistance of asphalt mixtures to load-induced deformation and fatigue cracking by constructing a three-dimensional physical gel network.

A study on the effect of microspheres on the freeze–thaw resistance of EPS concrete

open access: yesScience and Engineering of Composite Materials
This study investigated the influence of microbead dosages (0, 5, 10, 15, and 20%) on the frost resistance of expanded polystyrene (EPS) concrete. Five groups of EPS concrete specimens were prepared and subjected to rapid freeze–thaw tests.

Verification of damage model of ceramic matrix composites and analysis of cyclic deformation behavior

open access: yesNihon Kikai Gakkai ronbunshu, 2014
Ceramics are excellent in heat, abrasion and corrosion resistances, but their strength reliability for structural materials is not enough due to their brittle nature.

Freeze-thaw damage analysis of expansive soils based on natural strain damage model

open access: yesYantu gongcheng xuebao, 2020
The quantitative freeze-thaw damage analysis of expansive soils is of great practical significance for engineering in cold regions. In view of the unreasonable selection of strain model in the existing researches on soil damage model, the concept of ...

Damage test and model study of soft and hard interbedded rock based on piezoelectric ceramics and DIC

open access: yesMeikuang Anquan, 2023
In order to explore the damage evolution law of soft and hard interbedded rock after failure, three groups of rock-like test blocks (soft rock, interbedded rock and hard rock) were made by using the similar model theory.

Damage Localization of Conventional Creep Damage Models and Proposition of a New Model for Creep Damage Analysis.

open access: yesJSME International Journal Series A, 1998
After examining the ill-natured stress sensitivity of the conventional creep damage equations of Kachanov-Rabotnov, it was shown that this stress sensitivity is one of the most essential causes of damage localization and mesh-dependence in local approach of creep fracture analyses.

Fracture models as $\Gamma$-limits of damage models

open access: yesCommunications on Pure and Applied Analysis, 2013
We analyze the asymptotic behavior of a variational model for damaged elastic materials. This model depends on two small parameters, which govern the width of the damaged regions and the minimum elasticity constant attained in the damaged regions. When these parameters tend to zero, we find that the corresponding functionals $\Gamma$-converge to a ...

Evaluation of the Durability and the Property of an Asphalt Concrete with Nano Hydrophobic Silane Silica in Spring-Thawing Season

open access: yesApplied Sciences, 2018
In the spring-thawing season, the high frequency of freeze-soak-scour cycles in the short term is the main cause of pavement damage in the frozen region.
