Abstract
This master thesis os about reviewing fracture toughness investigation under pure mode I and mixed mode I&II loading for ductile materials. A first part composes a state of the art of the aforementioned loading modes. It consists in a historical mapping of the usual fracture criteria (at macroscopic scale) and a word of explanation for each one. A complete modeus operandi for carrying tests and compute toughness criteria is also developed. Concerning pure mode I loading, the standard method for fracture toughness is used with C(Tà specimens (ASTM E1820). For mixed mode I&II, tests are executed using an Arcan assembly mounted with CTS specimens and assisted by Digital Image Correlation (DIC), measuring in real-time the samples strain field. An experimental part exhibits and discuss results for tested materials (High strength steel provided with MnS inclusions and a stainless steel 316L). Finally, microstructure of both materials are investigated before and after tests.
