Review of time-dependent fracture model of concrete
矿业科学学报, 2021 The integrity of concrete structures under strong earthquakes and the stability of concrete structures with cracks are concerns of national security strategies.These two issues are closely related to the time-dependent fracture behavior of concrete.The ...

The Archimedes’ Constant, π Seen by Mechanical Engineers
Mathematical and Computational Applications, 2019 Probabilistic engineering mechanics is used to relate the value of π with one of the main parameters in fracture mechanics. It proposes an engineering method to obtain the value of it from engineering data without involving any geometrical ...

Modified Fracture Mechanics Approach for Hydraulic Fracturing Stress Measurements
Geofluids, 2020 Hydraulic fracturing (HF) test has been widely used to determine in situ stress. The use of a conventional continuum method for this purpose has raised considerable controversies concerning field tests, particularly in the determination of the maximum ...
