Brain drop simulation

Choose a channel featured in the header of iMechanica: 

I am doing research involving the finite element modeling of a human head namely Scalp, Skull, Brain & Duramater using Abaqus/CAE. I have finished modeling the parts, assigning the material properties, assembling and meshing the said model. I need to drop the whole assembly onto a 'floor'. What step should I choose. Also what interaction would I have to create so that the head would shear when it is dropped a distance less than 1 cm. Also bear in mind that it should not bounce.

 Thank you.

Good Time to Everybody, I am working on Thermoplasticity, especially thermoviscoplasticity, will be comparing the results of some basic examples problem worked be Simo and Miehe, modelled in Abaqus with the results of a locally developed code. I am new comer in this excellent forum and I am happy to see myself among a nice community of Mechanicians. I regard all those who are conneted in this form and those who helped in connecting this chain of  Mechanics.

Validation and benchmarking problems for 3D fluid simulation with free boundaries

I have a hard time finding problem sets for validation and
benchmarking of methods and codes for 3d fluid simulation with free
boundaries. Please guide me to (standardized) problem sets or key
litterture that is a suitable starting point. If there are not many
standardized tests I would like to initiate a dsicussion about what a
good test collection should be. I understand that iMechanica is focused
more on solid mechanics than fluid dynamics but the overlap is big.  

The Nobel, Graphene and 20% Google

Most prestigious engineering award

Physics, chemistry, and medicine have Nobel prizes. Mathematicians have fields medal. What do you think is the most prestigious engineering prize? Do we have any Nobel equivalent?

Fracture of electrodes in lithium-ion batteries caused by fast charging

During charging or discharging of a lithium-ion battery, lithium is extracted from one electrode and inserted into the other.  This extraction-insertion reaction causes the electrodes to deform.  An electrode is often composed of small active particles in a matrix.  If the battery is charged at a rate faster than lithium can homogenize in an active particle by diffusion, the inhomogeneous distribution of lithium results in stresses that may cause the particle to fracture.  The distributions of lithium and stress in a LiCoO2 particle
