Application of nanoindentation technology in rocks: a review (2020, background): “Geomaterials are hard to polish because of the mismatch in properties between their constituent phases (Mahabadi et al. 2012; Randall et al. 2009).”
Numerical Modelling of the Anisotropic Mechanical Behaviour of Opalinus Clay at the Laboratory-Scale Using FEM/DEM (2012, methodology): “In particular, a transversely isotropic elastic constitutive law was implemented in the Y-Geo FEM/DEM code (Mahabadi et al. 2012a) and a procedure to populate the model with a distribution of preferably oriented fractures was developed.”
Validation of a three-dimensional Finite-Discrete Element Method using experimental results of the Split Hopkinson Pressure Bar test (2014, background): “), rock blasting [5], seismic waves [6], packing problems, coastal protection [7],[8], dam stability [9], rock slope stability [10], masonry wall stability [11], and rock mass strength characterization problems [4],[12].”
Influence of microscale heterogeneity and microstructure on the tensile behavior of crystalline rocks (2014, methodology): “The fracture model uses cohesive crack elements along element boundaries and allows Mode I, Mode II, and mixed-Mode I-II cracking [Mahabadi et al., 2012a].”
