fis-2620	Triantis, Dimos; Kourkoulis, Stavros	Fracture precursor phenomena in marble specimens under uniaxial compression by means of Acoustic Emission data	2019	11	.pdf	application/pdf	7433	384	59	The values of the parameter A and the time constant τ of Eq.(3), as obtained by means of proper curve fitting, are equal to A=128.7 s-1, τ=0.98 s for stage B and A=141.6 s-1, τ=1.23 s, for stage D. As it is expected, the highest value of the time constant τ is observed in stage D due to the considerably increased acoustic activity that is recorded in this stage (recall that, after a while, fracture of the specimen occurred). In stage D, i.e., under constant stress of 63.5 MPa, the strain is increasing, at rates much higher compared to those of stage B.	cache/fis-2620.pdf	txt/fis-2620.txt
