Study on constitutive model of coal rock damage under graded cyclic loading and unloading
Taking coal as the research subject, the damage mechanical properties of coal were studied by grading cyclic loading and unloading tests. Using the Weibull statistical distribution and the introduction of damage variable D, a damage constitutive model suitable for coal at loading and unloading stag...
