Abstract: Representative volume (RV) of a composite material is important not only for experimental determination of materials properties, but also for theoretical analysis of various properties of the materials. RV is a random ...

Abstract: A distressed material can be considered as a two-phase composite material with the distressed areas (volumes) as one phase and the original material as the other phase. A parallel diffusion model was developed in which the ...

Abstract: To ensure safe operation of nuclear power plants (NPPs) during their extended service life, comprehensive investigation of the behavior of concrete structures and their components under long-term nuclear radiation is needed. ...

Abstract: Accurately forecasting the construction expenditure cash flow of transportation projects is critical for state departments of transportation (state DOTs) to secure sufficient funding to cover their fiscal obligations ...

Abstract: A mathematical model is established for chloride penetration in saturated concrete. The model takes into account various influential parameters such as water-to-cement ratio, curing time, types of cement, and aggregate ...

Abstract: The paper calculates how an aging concrete structure that has an uncertain constitutive law and random material properties responds to the random process of environmental humidity history. The time evolution of stochastic ...

Abstract: The basic creep of concrete is the time-dependent strain caused by a sustained stress in absence of moisture movements. It is the strain observed on sealed specimens. Similar to other properties of concrete, it is dependent ...

Abstract: The failure probability of structures must be calculated from the stress field that exists just before failure, rather than the initial elastic field. Accordingly, fracture‐mechanics stress solutions are utilized to obtain ...
