Ductile fracture prediction in Taylor Test
Mon, 2010-02-01 23:15 - sivaprasad.avs
I am reading the Weirzbicki's paper titled "Numerical Prediction of fracture in the Taylor test". I do not understand the terms stress triaxility and Lode angle parameter clearly. What does the term "negative stress triaxiality at -1/3" stand for? Kindly explain me these two aspects clearly and also provide some references for reading.
Thanks and Regards,

Stress triaxiality
Stress triaxiality denotes the ratio of hydrostatic stress and Von-mises stress. This might be in some textbooks, or with google, I find the following paper
On the Application of Stress Triaxiality Formula for Plane
Strain Fracture Testing. J. Eng.
Mater. Technol. 2002
Thank you for the information
Sir,
Thank you for the information and the paper.
