How to calculate Stress Intensity Factor for user defined material in abaqus?

Submitted by Rajwinder on

Dear all,

I need to calculate SIF in abaqus for some user defined material but I am getting the below error:

 ***ERROR: "*CONTOUR INTEGRAL, TYPE=K FACTORS" CAN NOT BE REQUESTED FOR A USER
           MATERIAL.

Is their any other process to calculate the SIF in abaqus, in case we use user defined material. Please guide me.

Thanks in advance

Quantification of ferrite-martensite interface in dual phase steels: A first-principles study

Submitted by Ali Ramazani on

The ferrite-martensite interfacial energy and equilibrium interfacial length as a function of martensite carbon content are assessed using first-principles atomistic simulations. The weight percent of carbon in the martensite phase was implicitly varied from 0.6 to 1.8 wt percent by modifying the lattice constant of body-centered tetragonal (BCT) martensite according to Kurdjumov and Kaminsky’s empirical expressions. With increasing carbon content, a decrease is found in both the interfacial energy and in the equilibrium distance between ferrite and martensite interfaces.

Abaqus VDLOAD/DLOAD

Submitted by mechapple on

I'm using the ABAQUS DLOAD subroutines, and I'm curious what the dimensions of the 

volume distributed body load should be. 

 

I understand ABAQUS uses [LT-2] for GRAV body loads. However, I'm curious if the 

units for BZNU acting over a volume should be [density]*[acceleration] or just

[acceleration].

 

Thank you,
