Study on a new inversion method for non-uniform distribution of rock material parameters
Combining the digital speckle correlation method (DSCM) with the finite element model updating (FEMU) method, a new inversion method of non-uniform distribution of rock material parameters is proposed to study...

Open AccessQuantitative investigation on the heterogeneity of deformation fields in sandstone pre-existing cracks during damage evolution
The inherently heterogeneous microstructures of rocks lead to heterogeneity of the deformation distribution within the rock volume. In this study, experiments were conducted on red sandstone specimens with fou...

A New Digital Speckle Correlation Method for Studying the Dynamic Fracture Parameters of Rocks under an Impact Load
In order to study the dynamic fracture behavior of rocks under an impact load with relatively low impact loading speed, a new method, the Node Interpolation Displacement Representation of Digital Speckle Corre...
