Experimental study of crack initiation and crack damage stress thresholds as critical parameters influencing the durability of natural porous stone (GA13-13967S)

The durability of natural stone is assumed to be intimately related to pre-peak fracture process (crack initiation and damage), which can be derived from stress-strain analyses prior and after the tests on porous rocks (sandstones, ...
