Estimation of the mode I fracture toughness and evaluations on the strain behaviors of the compacted mine tailings from full-field displacement fields via digital image correlation

•The fracture behaviors of the compacted mine tailings were presented in the paper.•Mode I fracture toughness of the compacted MTs were presented using various methods.•Strain behaviors of the compacted MTs were evaluated by using 2D DIC method. Ore beneficiation processes produce huge quantities of...
