Abaqus UGENS/UMAT for composites damage

Submitted by ebarbero on
A discrete damage mechanics (DDM) model is now available as a UGENS/UMAT implementation for Abaqus/standard. This is an analytic constitutive model for laminates composites, based on discrete fracture mechanics. It is capable of predicting matrix crack initiation and crack density evolution using just two parameters--the critical energy release rates (ERR) in opening mode I and shear mode II. A methodology is available to determine those (invariant) material properties from experiments.

ANSYS APDL query

Submitted by sbmarwadi on

hi

I want to determine the number of cycles required to propagate a crack upto certain dimentions or vice-versa?

Does ansys APDL has that capability to do fatigue analysis of a growing crack.

my problem is analysis of elliptical corner crack present at shell nozle juntion. 

if yes,please tell what is to be done in ansys  13.0 APDL for this?

thanks and regards

hashin damage

Submitted by h1a9d9i0 on

hi.

Im modeling a composite with hashin damage.

but I dont know what to insert to the hashin damage

requirements .for example I dont know what to insert to the

 fiber tensile strength or   fiber compressive strength and so on. please help me
