International audience; 15 2 Heat and moisture are known to have important mechanical effects on polymers such as hygric 16 swelling, thermal expansion and mechanical weakening. A common approach when 17 investigating such effects is to assume the ef

Rocks under stress deform by creep mechanisms that include formation and slip on small-scale internal cracks. Intragranular cracks and slip along grain contacts release energy as elastic waves termed acoustic emissions (AE). AEs are thought to contai
