Effect of triaxial stress distribution upon roughness of brittle fracture surface [PDF]

MATEC Web of Conferences, 2019
To observe the effect of stress triaxiality upon brittle fracture surface, we performed two types of experiments which differ in stress triaxiality. As a result, crack branch starting speed changes in two specimens and the speed was affected by stress ...
