regarding composite modeling under impact

Submitted by MM Ansari_IITR on

Hi,

i make a model of 3d composite plate with analytical rigid impactor . i used continuum shell element (sc8r element).

my model is not failed even at high velocities. i am not understand why,,,

any one help me..

 

Hello

I do not know the answer to your last question.

 

But you can get a subroutine code for the Hashin criterion from:

1) FINITE ELEMENT ANALYSIS OF CARBON FIBER COMPOSITE RIPPING USING ABAQUS

In Partial Fulfillment of the Requirements for the Degree Master of Science Mechanical Engineering

2) Register on http://simulia.custhelp.com
and read Answer ID 3123 Abaqus/Explicit VUMAT for the simulation of damage and failure in unidirectional fiber composite materials

Good luck
