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.

Single side damage simulations and detection in beam-like structures [PDF]
, 2015 Beam-like structures are the most common components in real engineering, while single side damage is often encountered. In this study, a numerical analysis of single side damage in a free-free beam is analysed with three different finite element models ...

New methodology for calculating damage variables evolution in Plastic Damage Model for RC structures [PDF]
, 2017 The behavior of reinforced concrete (RC) structures under severe demands, as strong ground motions, is highly complex; this is mainly due to joint operation of concrete and steel, with several coupled failure modes.

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.

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

Statistical properties of fracture in a random spring model [PDF]
, 2005 Using large scale numerical simulations we analyze the statistical properties of fracture in the two dimensional random spring model and compare it with its scalar counterpart: the random fuse model.
