Hows does Abaqus calculate the Stress Intensity Factors?
Hows does Abaqus calculate the Stress Intensity Factors?
(OP)
Dear All,
I have been calculating Stress Intensity Factors with Abaqus and they compare very closely with close form solutions, for different mesh densities and element types. The question I have is: would anyone know which method does Abaqus use to calculate Ks? The Abaqus Theory Guide only describes how the J-Integral is calculated.
Thank you in advance for your help,
-Francesco

..This standards has an extensive literature regarding stress intensities and their application for fitness for service purposes.
take care and thanks

Anyway, I have answered my original question. Unlike other codes, Abaqus calculates the stress intensity factors from the J-integral, so it calculates the J-integral first.
