A probabilistic computational framework for the prediction of corrosion-induced cracking in large structures
Stress corrosion and SCC mechanism The stress corrosion process, as shown in Fig. 2, starts from the local breakage of the passive film. Under a corrosive environment, the metal is corroded and produce cations (\({M}^{+}\)) into the electrolyte as well as the electrons in the electrode. During service life, complex mechanical […]
CSRWire – Energy Efficiency of Buildings
Published 12-27-22 Submitted by Ericsson Summary The value of properties is largely impacted by the energy efficiency of the buildings. With the help of IoT, energy optimization is becoming one of the most efficient ways to reduce energy use, and as a result, increase property value and cut CO2 emissions. […]
