Data for: A New Fracture Model of Reservoir Ice Layer in Northeast Cold Region of China
Description
The data was about ice crack and farture. The cracking and fracture behaviour of ice material in cold regions significantly affects the mechanical properties of concrete material and structures due to ice pressure or the ultimate load carrying capacity. The mechanical performance of ice material depends on the characteristics of ice crystals, ice depth, temperature and geographical distribution in different regions. The main objective of this paper was to propose an innovative model for describing the fracture toughness of ice material subjected to different geographical distributions, depths and temperatures based on the energy balance theory, the generalized self-consistent method and Gurson’s damage model, and the model results were then compared with experimental results and those of Ji. In addition, according to statistical theory, an equation for calculating the variance of the fracture behaviour of ice material was established based on the fracture flexibility results for determining the mechanical properties of the ice material.
