“…Among them, the cracking of mass concrete structures caused by temperature is also being paid more and more attention to by people in the fields of water conservancy and civil engineering. At present, the research on the working behavior and cracking of concrete structures under mechanical load is relatively thorough, and the research on the cracking of concrete structures at the macroscopic scale caused by temperature has also made many achievements, see, e.g., [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 ]. However, concrete is a multiphase composite material consisting of cement, sand, stone, and water.…”
