I'm posting a few experimental studies we have conducted on the dynamic behavior of hierarchical fibrous materials, using vertically aligned carbon nanotubes as a model material. I hope these will be useful to those who are interested in buckle-instabilities, multiscale behavior, and energy absorption mechanisms.
An overview:
Applications are invited for a fully funded PhD studentship at the University of Manchester to help develop the next generation of simulation tools. These will be used to evaluate the structural integrity of novel aerospace composites under a wide range of operational conditions. The student will join a €3-4M euro research project that has recently been funded to investigate the use of biomaterials in aerospace composites. The project involves a range of academic and industrial partners in Europe and China, providing many opportunities for overseas research visits.
http://dx.doi.org/10.1016/j.jmps.2015.11.008 Metallic thin-walled round tubes are widely used as energy absorption elements. However, lateral splash of the round tubes under impact loadings reduces the energy absorption efficiency and may cause secondary damages. Therefore, it is necessary to assemble and fasten round tubes together by boundary constraints and/or fasteners between tubes, which increases the time and labor cost and affects the mechanical performance of round tubes.

Hi friends, I'm new here and also new using abaqus.
I need to do my final project about bird strike analysis using abaqus. But for now, I try to follow the tutorial from youtube about impact bullet first. For some trial sometimes i found errors and never succeed to solve it. Included the impact bullet trial. This is what i've got:

Dear colleagues,
I am organizing sessions related to “Composite Armor” and “Impact Dynamics” at the following conferences in 2014. I would like to personally invite you and your research group to submit an abstract.
The Composites and Advanced Materials Expo (CAMX) (ACMA/SAMPE)
Abstract submission deadline: Feb 7, 2014
Session Title: Composite Armor
American Society for Composites (ASC) 29th Technical Conference
Abstract submission deadline: Feb 1, 2014
The Department of Engineering Science at Oxford University has recently obtained an iCASE studentship funded by EPSRC and Rolls-Royce plc to perform research into the mechanical behaviour of metals at high temperatures and high strain rates. The studentship provides full funding (fees and stipend) at the home / EU level for 3.5 years.
Dear All,
we have a DPhil studentship available in the Solid Mechanics and Materials Engineering Group, within the Impact Engineering Laboratory led by Prof Nik Petrinic.
Hi All,
While using LS-DYNA to simulate the impact damage of composites, I have a question about modeling.
I plan to create the model by solid element. Each ply has one element in the thickness direction. The contact between plies is *contact_automatic_surface_to_surface_tiebreak. My question is how to create separate ply models while using this contact. It is clear that common nodes are not allowed. So there might be two possibilities.
Dear all，
