Postdoctoral Position Available at University of Western Ontario,Canada

Position is available for a postdoctoral fellow to carry out an industry sponsored project on carbon fiber composite modeling. The contract is initiated for one year, with possible extension if work progresses satisfactorily. The research will focus on

 (1)  micromechanics modeling of elastic and viscoplastic behavior of injection molded carbon fiber composites;


 (2)  homogenization techniques and constitutive model development for vibration, strength and impact simulations of carbon fiber composites.

Comparing experimental fracture properties and micromechanical (or global-local/multiscale) finite element simulations

I am interested in developing a global-local finite element model (micro/macro) to simulate flexural testing of a composite material. Flexural loading will be applied on global model (macro) and crack propagation will be simulated in the local model (micro). I want to compare stress intensity factor or any other fracture property obtained from local model (micro) with that of experimental results.

I would appreciate if anyone could suggest some references/literature in this area. Any kind of suggestions would be great!

How to find material parameters for Abaqus PDA

The PDA model implemented in Abaus is an implementation of the idea of the cohesive zone model (CZM), which is quite popular for the analysis of delaminations, but PDA is for intralaminar damage. The problem my group faced when trying to use PDA was "where do we get the material parameters?"  We asked around in blogs and such but could not find a definitive answer. So, we went to work and came up with a methodology that may serve you.

New book: FEA of composites using Abaqus

New textbook includes an explanation of the concepts involved in the detailed analysis of composites, a sound explanation of the mechanics needed to translate those concepts into a mathematical representation of the physical reality, and a detailed explanation of the solution of the resulting boundary value problems by using commercial Finite Element Analysis software such as Abaqus.

After researching a lot, Even after researching a lot, I haven't been able to find a damage criteria which  can depict natural failure in of a fiber. I do not want to induce a crack in it and break it or put in a cohesive layer. I want to break it as it breaks naturally.

flexural rigidities of orthotropic composite laminates

Choose a channel featured in the header of iMechanica: 

Dear all,

Iam working in composite orthotropic laminates consists of many plies having different material properties in each ply. How to determine or calculate the flexural rigidity (D) of this laminate by transforming these composite into an isotropic model. The idea is that flexural rigidity of the orthotropic laminate is being smeared into a single isotropic formulation.

For instance: if I have three plies:

Ply1 : D1x and D1y

Ply2: D2x and D2y

Ply3: D3x and D3y

energy balance of surface-based cohesive of composite under impact in Absqus 6-10

Hi there! I am really new to Abaqus and I need to model a composite
laminated crash cone under impact to a flat solid wall (analytical
surface is used). I modelled a cone with a layers of conventional shell
elements with hashin failure criteria and surface-based cohesive
behaviour as interaction between layers representing the interface of
composite laminates. The model runs successfully but once I checked the
energy balance, the damage dissipation energy from the cohesive, it
turned out to be NEGATIVE (I think this is wrong).
