composite

A graduate position is opened in Advanced Hierarchical Materials by Design Lab at Louisiana Tech University on multiscale modeling of composites. The candidates must have earned a degree in Mechanical Engineering or related fields, and be a US Citizen. Candidates with a solid background in theoretical and computational mechanics, specifically continuum mechanics and finite element modeling are preferred. Familiarity with FEM software package COMSOL is a plus.

hello 

am looking for a phd position in compututional mechanics i have a good backgroun in numercial simulation and mathematical modeling with MS in mechanical engineering i was working in many topic from material modeling (dammage ,metal forming ...) composite modeling and simulation (continue element of composite shell in high frequency,hommoginazation method crush simulation ,... ) i have a experience in biomechanic modeling and simulation 

i have a good programming skills : fortran c++,python 

finite element ,boundary element,xfem

A 12 months post Doctoral position is avalaible on mechanical and numerical modeling fields at LSPM, univ. Paris 13, France.

The aim  is the development of a theoretical and numerical modeling approach in order to describe the mechanical properties of polymer composite material and structures reinforced by CarbonNanoTube. Once the description of mechanical properties achieved, the extension of the modeling  framework to the electrical and thermal properties and their coupling to the mechanical behavior might be considered.

Trying to model a crossply square plate with a sinusoidal temperature loading (uniform along the thickness). I am trying to match the results by Kant et al 2008 and Rohwer et al 2001. I am modeling the compoosite as a 3-D solid elements (making a part and dividing into 4 layers). I always obtain transverse shear stress on the 90 degree layer at 0,b/2,z to be zero.  My results match with that of the paper when I have a single layer of orthotropic material but they dont match when I have 4 layers of equal thickness and an aspect ratio of 5 (length/thickness).

Hi every body,

I'm tring to make a beam by using beam elements in Abaqus like this:

Hello

I am using Abaqus/CAE 6.10 to simulate a Debonding test (cohesive behavior for composite delamination). 

I ran a Abaqus debonding simulation example (from Abaqus online documentation - Abaqus Benchmark Manual - 2.7.1 Delamination analysis of laminated composites).

The Abaqus/Explicit three-dimensional model with surface-based traction-separation behavior used a surface contact interaction property with:

- default Cohesive behavior

- XFEM-based LEFM (using VCCT) fracture criterion.

Hello,

I modelled a 3-D DCB (Double Cantilever Beam) test specimen to simulate crack propagation (delamination) in composite materials.

To do so, I used surface cohesive properties between plates in Abaqus/Explicit, and applied a displacement at the plates tips.

When I used continuum shell elements the crack propagated as expected and the delamination occurred.

Hi,

I am working on short glass fibre reinforced composites.

Is there a material model which can predict the fatigue behaviour of the composite structure at high temperature.

Thank you

Regards

Is
there any one here who could help me through the step-by-step creating and analyzing
a 3D simulation of ballistic, full penetration impact of a steel, rigid
projectile into the 3D composite plate?

note1: as i know,
available HASHIN damage model in ABAQUS isn't an appropriate tool to do
that. because it has an important restriction that confined you in the
"2D" damage analysis of composites and using 2D planar elements only.
