A hydro-mechanical approach is developed to investigate progressive fracture damage study with flow behavior in PMMA sample. A series of experiments are conducted to replicate the field work of hydrofraturing process. The PMMA (poly methyl methacrylate) specimens have been performed to simulate to fracture developments that are similar to hydrofraturing process. These Fractures are mechanical breaks in rocks involving discontinuities in displacement across surfaces or narrow zones. The Micro mechanical factor which influences the new crack and porosity generation is heavily influenced by the high pressure, temperature and injection hole diameter on the PMMA sample. This combined technique of Pressure (N/mm2), Temperature (C) and Injection hole diameter (mm) are robust and yields consistent in fracture length (mm) development during all the series of experiments are conducted. The fracture propagation can be easily visualized through the PMMA samples. The maximum fracture length observed as 580mm.
