As i remarked on another snippet. You basically don't know what you're talking about. The transition from localized failure to global failure of the structural system isn't time dependent. Its load dependent, and that dependency further breaks down to load type, path, and magnitude and they're interelated. These factors rely on understanding how the design works which youre completely skipping in your effort to rationalize "CD" as the only explainable mechanism
