Effect of Stochasticity on the Damage Accumulation in Solids
International Journal of Damage Mechanics, 1994The influence of stochasticity of external action on damage accumulation is studied in terms of CDM. The accounting for microscopic mechanisms is based on the introduction of additional parameters—traditional damage and shear damage. Kinetic equations of damage accumulation are reformulated to account for the stochastic compo nent of loading.

Silicon carbide/ silicon carbide ceramic matrix composites (SiC/SiC CMCs) are a subgroup of structural ceramics that are well-suited for high-temperature aerospace applications, due to their low weight, excellent creep resistance, damage tolerance, and high specific strength.

Markovian modeling of seismic damage accumulation
Earthquake Engineering & Structural Dynamics, 2015SummaryAnalysis of civil structures at the scale of life‐cycle requires stochastic modeling of degradation. Phenomena causing structures to degrade are typically categorized as aging and point‐in‐time overloads. Earthquake effects are the members of the latter category this study deals with in the framework of performance‐based earthquake engineering ...

A Method for Conservative Damage Estimation Based on Linear Damage Accumulation
2019 4th International Conference on System Reliability and Safety (ICSRS), 2019To estimate the reliability of cumulated damages, probabilistic models are usually needed. However, the sum of random variables is difficult to calculate. In this paper, a framework to conservatively estimate the reliability of cumulated damage is established based on algebraic sum of quantiles of damages.

Risks of Accumulated Environmental Damage
Issues of Risk Analysis, 2023The article deals with the issues related to the accumulated environmental damage that was formed on the territory of Russia during the Soviet era and after the collapse of the USSR, the decision on the elimination of which is only being planned at the present time. This damage is due to the lack of attention on the part of the state and enterprises of

Damage Accumulation in Glass Plates
Journal of Engineering Mechanics, 2002This paper examines the glass cladding damage accumulation caused by wind loading. The primary focus is the effect of the non-Gaussian nature of wind pressure fluctuations. The damage is estimated using the Monte Carlo methodology and Brown's integral formulation.

Damage accumulation in structures
Reliability Engineering, 1987Four types of defect are described, and the hierarchical nature of shape, form and material is explored. Defects and failure are also shown to be hierarchical, and a structure's damage is defined as the sum of its defects. The concept of material toughness is linked to structural redundancy. Damage is described in two ways: geometrically and materially,

Model of Fatigue Damage Accumulation
Key Engineering Materials, 2014In this paper, the analytical method of fatigue life estimation of gear teeth is proposed. The computational model of fatigue damage accumulation was built using the adequate NASGRO 2/3 formula, moreover Formans and Paris-Erdogans laws were utilized for comparison. The ranges of stress intensity factor were determined using the boundary element method.

Accumulation of radiation damage in plutonium
Cryogenics, 1962Experiments were carried out which show that the resistivity of plutonium increases while the specimen is being held at helium temperatures. The electric resistivity on first cooling to helium temperatures increases between room temperature (290 deg K) and liquid nitrogen temperature (77 deg K) and thereafter decreases to the liquid helium temperature (
