From: Calculation method of HJC constitutive model parameters of natural joint angle slate
Parameter fitting of HJC constitutive structure model. (a) Variation pattern of uniaxial compressive strength fc with slate joint angle; (b) variation pattern of fracture pressure Pc with slate joint angle; (c) variation pattern of crushing volume strain μc with the slate joint angle; (d) variation pattern of shear modulus G with slate joint angle; (e) variation pattern of characteristic pressure hardening factor B with slate joint angle; (f) variation pattern of standardized pressure hardening N with slate joint angle; (g) variation pattern of characterized cohesive strength A with slate joint angle.
