fracture mechanics cohesive abaqus crack length

Hello, All

***Problem ***

Failure pressure for Steam generator tube having 2 axial cracks. I am following one paper in that paper they found failure pressure by finding J and K values for line spring elements for different pressure. The pressure at which it approach material JIC(92N/mm) and KIC(65Mpa*sqrt(m)) value is considered as failure pressure or coalescence pressus

Hi

I have a working DCB model with embedded cohesive elements. This is done in Abaqus/CAE standard using nonlinear analysis.

However I'm having trouble finding an efficient way of measuring the distance of failed cohesive elements from the load(displacement) line for evey time increment in abaqus. Its possible to do this manually using the 'Query information' tool for every single time increment but for a model with more than 100 frames this method is not very good.
