Hello everyone,

Can someone please explain the difference of these two?

Thanx

Can some of you recommend a source to learn about Discontinuous Galerkin FEM?? I am specifically interested in its application in geomechanics but I need to learn the basics first!

Hi dear mechanicians,

I am about to publish the results of my MSc thesis in a journal. The thing is, my project was carried out in industry about multi-scale FE simulation of impact in composites. So it is merely an industry-level application of available methods.

 I want to ask if any of you have any particular journal in mind, in which publishing such a paper is rather easy (doable) and does not have a long waiting list for review??

Looking forward to your suggestions

Thanx a lot

Hi everyone,

According to a book chapter written by NL Hancox, 'Laminar construction of composites which is required if the reinforcing fibres are to be used efficiently and anisotropy reduced, can be a reason why composite laminates are vulnerable to impact damage.'

Now I have three questions;

1-What is meant here by the specified 'laminar construction to reduce anisotropy'?Does it mean to use different orientation for fibres in each ply to have an isotropic material at the laminate level?

2-Why are we interested to make laminates isotropic at all?

3- How can this, make composite laminates more susceptible to failure under impact??

Hello Everyone,

I have a question and I really appreciate any comment:

Hello Everyone,

I am a beginner in FEA of composites under impact in commercial explicit code Pam Crash.I want to know why the behaviour of composite plies with CDM approach show mesh dependency?Or a more general question for me is that what makes the FE simulation of a material with strain softening behavior mesh dependence(If this conclusion is right)? Does it make any difference with regard to mesh dependency if one uses implicit codes??

Thanks
