A Size Effect Model Combining Both Surface Effects and the Fracture Process Zone (FPZ) for Rocks under Uniaxial Compression

open access: yesApplied Sciences
Developing a size effect model that can encompass the surface effect and the fracture process zone (FPZ) is still challenging. Here, a combined size effect model (CSE model) is formulated by integrating the surface effect size model and the size effect ...
