Dear List Members,

Enclosed below are the summarised replies to my question on 15th April 2003.

Original Question:
I am presently conducting research on human injury biomechanics due to
blast. Does anyone know of any simulation program(s) that integrate a fluid
dynamics code (for modelling blast situations and effects) and a structural
mechanics code (for modelling whole body and/or tissue biomechanics) to
predict injury on humans exposed to blast?

Does anyone also know of any existing injury or tolerance limits to assess
human trauma due to blast overpressure and induced acceleration? If you are
presently conducting such research, I will be pleased to hear from you too.

Thank you in advance for your time and kind assistance. I shall post a
summary of replies for interested Members.

I am working at TNO Prins Maurits Laboratorium. TNO-PML is part of the TNO
Defence Research Organisation.
My working field is the injury biomechanics, i.e. occupant safety in vehicle
mine protection, non lethal weapons, non penetrating impacts, bullet
threats, etc. etc. .

This year I will start a study on blast injuries. The topics you are talking
about are research topics here as well.

Computer codes: Autodyn, LSDyna
Human body response: MADYMO

>From Georges Limbert

There are some excellent codes to carry out the type of analysis that you
are interested in:

1. PAM-CRASH/SHOCK (SOLID) & PAM-FLOW (FLUID) developed by ESI Group company
(www.esi-group.com) are 2 codes
that work in combination to treat coupled fluid-structure interaction
problems. The combination is very efficient and has already been used
for biomechanical problems.

2. DYNA3D (www.lstc.com) combines solid and fluid interactions in the same
code(arbitrary Eulerian-Lagrangian method)

These two codes are explicit and are both suited to the modelling of highly
dynamic and nonlinear phenomena.

ANSYS (www.ansys.com) has multiphysics capabilities but I do not know this
code well enough to say whether it is suitable for blast analysis. It
probably is in combination with ANSYS DYNA but you should check this.

My research interests are centered around computational methods (finite
element) in biomechanics, nonlinear continuum mechanics and mechanics of
biological tissues. I am currently particularly interested in the modeling
of damage to soft tissues (skin, ligaments, tendons...) under highly dynamic

Let me also take this opportunity to do a bit of marketing !!!! I am
actively involved in my engineering consultancy company which provides
customised computational solutions for all the industrial sectors where the
numerical modelling of biological tissues is of relevance (orthopaedics,
biomedical, automotive, defence...): www.firstnumerics.com

Could you try ADINA?

>From Jean-Philippe Dionne
This is in response to your message sent to the BIOMCH-L mailing list. Our
company is actively involved in the design/development and manufacture of
protective equipment against blast related threats, for both explosive
ordnance disposal and demining purposes. As such, we have studied the
effects of blast injuries, and how injury predictions can be made based on
pressure and acceleration measurements on anthropomorphic manikins. We do
not have any physical or numerical models for the response of the human body
to blast, but we have some experimental data that we have compared with
known injury thresholds either from the automotive industry, or from blast
testing studies from the 1960's.

We would be interested in learning more about your interest in this area,
and possibly exchange information. Please do not hesitate to contact me

I have found some articles that may be of use in research on the requested
topics. Two of the articles may be reached at the following web addresses:
