Johannes Aichele’s 2019 PhD paper
“Elastic waves in complex conditions: From
the onset of rupture to viscous dispersion
in foams”, had all the keywords I was looking for:
“Acoustic radiation” stick-slip slow-wave
I’d just learned about “Acoustic Radiation” from TRIZ Effects database when searching how to SEPARATE a FIELD
and “Surface Acoustic Wave” came up, which looked a LOT like the “slow wave” that proceeds disaster with a stick-slip event – or a violin playing.
Hoping it covers the “onset of rupture” portion as that’s what my main concern is: prior to oscillation part.
