German term or phrase: Laborbruch + Ermüdungsbruck + Restbruch
Proben entnommen: Laborbruch unterhalb der Ermüdungsbruch...Restbruch nahe der zusammengelaufenden Bruchfronten
Michael Dollman
English translation:See below
Explanation:
Bad news first:
I have no documented solution to "Laborbruch" - but it could be a fracture induced by the laboratory as part of the testing procedure.

Ermüdungsbruch: fatigue fracture (verified by dictionary)

Depending on the rest of the text or the situation), one of the following variations (all verified by dictionary) might be appropriate: fatigue crack, fatigue damage or fatigue failure.

Restbruch: final break
I tried Google and found this at a bilingual site (about bicycles! - link below under References):

... Bei Fertigungsfehlern oder unzureichender Dimensionierung kann es zu ERMÜDUNGSBRÜCHEN der Kurbel, der Achse oder der Verbindung zum Kettenrad kommen. Da der RESTBRUCH meist unter Wiegetritt-Beanspruchung erfolgt, ist das Unfallrisiko entsprechend groß.

... Manufacturing faults or insufficient dimensions can cause FATIGUE FRACTURES in the cranksets, the axle or the connection to the chain wheel. The FINAL BREAK usually then occurs when riding out-of-saddle and thus the risk of sustaining a serious accident is high.

I hope this helps.

Explanation:
Stölzel, WB Metallurgie und Gießereitechnik, gives these terms:
Restbruch - residual fracture, ultimate fracture, final fracture
Restbruchfläche - residual fracture surface

Looking at your sentence above, residual fracture would fit in quite nicely

Ermüdungsbruch - fatigue fracture or endurance fracture

As for the elusive Laborbruch – not in any dictionary, but I did find "laboratory fracture" under the following URL:
