An extension of the damage model [PDF]
Metrika, 1982 The damage model was introduced byRao [1963] and is based on the assumption that an original observation is subjected to a destructive process. Rao, examined in detail the case where the distribution of the original observation and the destructive process were Poisson and Binomial respectively with fixed parameters.

Damage in fiber bundle models [PDF]
The European Physical Journal B, 2000 We introduce a continuous damage fiber bundle model that gives rise to macroscopic plasticity and compare its behavior with that of dry fiber bundles. Several interesting constitutive behaviors are found in this model depending on the value of the damage parameter and on the form of the disorder distribution.

An Exponential Model for Damage Accumulation [PDF]
Communications in Statistics - Simulation and Computation, 2009 In this article, we present a general model for predicting the fatigue behavior for any stress level and amplitude using the exponential model. Based on the Wohler field for fixed stress level, a compatibility functional equation enables us to derive the general model with eight parameters. The problem of parameter estimation is then discussed and some

Plasma model for charging damage [PDF]
Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1995 The mechanism responsible for charging damage to integrated circuit device insulators is treated as a plasma phenomenon, in which the beam/plasma drives potential differences on the process surface. J−V data obtained with the CHARM2 diagnostic in a high current implanter (flood OFF) are fit with a plasma probe model.

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.

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.

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
