Abstract: There is large experience on the determination of crack propagation initiation parameters in SCC and HE scenarios by fracture mechanics tests. Although there are satisfying experiences, the estimation of a parameter in those situations by Small Punch means is in continuous research. In this work a new approximation for the parameter KEAC is presented. It is based on the energy for embrittlement damage initiation on notched Small Punch specimens in SCC and/or EH conditions. Likewise another key aspect is analyzed, as it is the punch rate for SPT in aggressive environments, aiming not to have an influence on propagation mechanisms. Finally, bases for future research in this field are established.
