A chemo-transport-damage model for concrete under external sulfate attack
, 2020 Sulfate-induced deterioration can reduce the service life of a concrete structure. A coupled chemo-transport-damage model for external sulfate attack is developed, which predicts the effects of calcium leaching and temperature on the deterioration ...

Tree‐based flood damage modeling of companies: Damage processes and model performance [PDF]
Water Resources Research, 2017 AbstractReliable flood risk analyses, including the estimation of damage, are an important prerequisite for efficient risk management. However, not much is known about flood damage processes affecting companies. Thus, we conduct a flood damage assessment of companies in Germany with regard to two aspects.

Damage Model of Basalt-Fiber-Reinforced Cemented Soil Based on the Weibull Distribution
Buildings, 2023 This study investigates the mechanical performance and a constitutive model of basalt-fiber-reinforced cemented soil (BFRCS) containing 0%, 0.1%, 0.3%, 0.5%, and 0.7% basalt fibers with lengths of 3, 6, 12, 20, and 35 mm, respectively.

Gradient Damage Models for Heterogeneous Materials
SIAM Journal on Mathematical Analysis, 2023 In this paper we study the asymptotic behaviour of phase-field functionals of Am brosio and Tortorelli type allowing for small-scale oscillations both in the volume and in the diffuse surface term. The functionals under examination can be interpreted as an instance of a static gradient damage model for heterogeneous materials.

Experimental study on relationship between impact damage of sandstone and stress wave parameters
矿业科学学报, 2018 Split hopkinson pressure bar (SHPB) was used to test the dynamic property of sandstone under different impact speeds and wavelengths.The results showed that for the same length of impact wave，the greater of the impact velocity could result in the greater

Reinforcement calculation of concrete slab in concrete faced rockfill dams
Yantu gongcheng xuebao, 2023 The stress and deformation safety of the concrete slab is crucial to the concrete faced rockfill dams (CFRDs), however, most of the traditional methods do not consider the effects of the reinforcement in slab, therefore, the calculated results can not ...

Damage process modeling on SMC
Journal of Applied Polymer Science, 1996 The damage processes taking place in SMC, which has been subjected to monotonically increasing tensile loads, are analyzed and the stress-strain curves are calculated. SMC is viewed as a laminate consisting of fiber bundles embedded in a resin/filler matrix.

Accelerating fatigue simulations of a phase-field damage model for rubber
, 2020 Phase-field damage models are able to describe crack nucleation as well as crack propagation and coalescence without additional technicalities, because cracks are treated in a continuous, spatially finite manner.
