Effect of Reinforcement Corrosion on Structural Behavior in Reinforced Concrete Structures According to Initiation and Propagation Periods by Seda Akduman, Hakan Öztürk

“…The most important parameter influencing the corrosion mechanism is the corrosion rate, while another important factor is the formation of cracks on the element surface. In cases where cracks are present, the corrosion initiation time is shortened, which means that materials should be selected at the design stage that are suitable for the environment, and the years of maintenance required should be calculated by the design engineers. …”

On Heat and Mass Transfer within Thermally Shocked Region of Enhanced Geothermal System by Kamran Jahan Bakhsh, Masami Nakagawa, Mahmood Arshad, Lucila Dunnington

“…Thermal shock occurs when the cold water contacts the hot rock near the injection borehole, creating a network of small, disorganized, closely spaced micro cracks. As the cold-water injection continues, the hot rock cools down and the micro cracks coalesce, becoming a better-defined network of thermal fractures. …”

三明治型中心裂纹试样性能失配对材料拘束作用范围的影响研究 by 戴悦, 杨杰, 陈浩峰

“…Different property mismatched laboratory specimens with sandwich structure and center crack that contain the single-edge-notched bend（ SENB）,compact tension（ CT）,single edge-notched tensile（ SENT）,and central-cracked tension（ CCT） specimens were selected,and the FEM simulations based on GTN（ Gurson-Tvergaard-Needleman） damage model were used to further investigate the influence of property mismatch on the effect range of material constraint.The results show that the numerical value of the effect range is also influenced by the property mismatch.The effect range increases with increasing of the property mismatch.In addition,the strength of property mismatched structure has buckets effect,and the buckets effect is more obvious in high property mismatched structure.In the future,the correlation of the effect range of material constraint with geometry constraint and material constraint should be established,and the results can provide scientific support for the structure integrity assessment and the design of property mismatched structures.…”
