Hello everyone,
I am trying to model a DCB (mode-1) test for a carbon-fiber composite sample on Ansys. However, I am very new to modelling and finite element analysis and I am a bit struggling.
As far as I know, it is possible to see the failure types based on some failure criteria. So, is it possible to get the time of the failure (fiber breaking, matrix cracking etc.) ? For example, could we know when the first fiber breakage occurs ?
Any help would be appreciated. Thank you very much.
Dear sir
Please read, may be useful to you
in this various stresses are given with respect to time, we should assume that the failure occur at maximum stress, so the time required to reach the max stress, is the time of failure
Are you accounting for inherent scatter in the input data? One model will provide a single answer. The real world test will generate a very wide range of failure times. And in the test, your load is very well controlled. Which material properties do you know well enough to estimate their influence on the scatter of the failure time?
Doug Hall Actually what I am looking for is the very first time that the fiber breakage or matrix cracking occur according to some failure criteria.
