Thanks for your comment. It is stated in the video that if the criteria equals or exceeds 1,failure occurs according to hashin. I am working on an update of the video which will include element deletion, so the damage is more obvious. Also it will include more details on modeling and why. Thanks for your advice For the equation constraint to work you need to define the dof of the intended loading.

@@hnrwagner Sorry sir it might be presumptuous but even for me who has worked with abaqus for around 6 years the videos seem to be fast. For example, you just choose the options without any specific elaboration. I just asked two questions in my comments for this video. If you look at them and turn back to see the videos you would notice that you just choose and continue. By the way your voice is also hardly heard!
