Abstract
Method for predictive determination of load, simple or combined, at rupture, of a structure, which includes subjecting the structure to a stress which is equivalent to the load; recording acoustic activity generated by damages suffered in the structure, up until a pre-determined stress threshold; and determining the predictive value of the load at rupture using the recorded acoustic emission based on a relationship linking time to the load.
