Total Strain Energy Density - MARC

[BespinSunset]

I've been working using MENTAT/MARCK7 to create a 3D model of a bi-material interface and the effect of cracks around this interface. I was wondering if anyone could help me in finding out how exactly the Total Strain Energy is calculated in the case of an 8 noded 3D Element.

Thanks,
Bespin

I would look at the book by Bathe 'Finite element analysis' or any equivalent. It all depends on the shape functions they are using, whether it is hybrid or not, etc.

I know it is easy to calculate in ANAYA
