Hello everybody,

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.

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

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

Hi,

 I am Ghouse, I am working on modeling crack initiation and propagation of RTV (room temperature vulcanization) joint and this joint is present between two automobile engine components. My first question can I use cohesive zone modeling for simulating this problem, If yes, how to get the cohesive traction-separaion properties of this joint. Since this is the real world application which involves bond between a cast iron component and an aluminum component. Can I use the standard test like DCB test or End notched flexure or similar standard test to obtain the traction-spearation curves or the test need to be performed on the actual parts.

I want to model wire rope/sling as 1d-element in abaqus.

let me know the suitable 1d-elemet for wire rope/sliing.

Please apply online. Do not contact me; I do not work in the company.

I need to know how to to determine the work needed to push  water through a 20 foot thinwall plastic tube ( Polyethylene) with an inner diameter of 4 mm at a rate of 100, 250 and 500 mL/minute. The tube is level throughout. What pressure will I need? How much energy does this take ? Accuracy not needed just an approx figure will be fine at this time, as we will run testing later. The reason for need this is to select a pump for the job.

Thank you so much .
