electro-mechanical properties of the 3M VHB electro-active polymer tape
Dear modellers
do you work with electrostrictive polymer actuators and need their properties for your simulations? If so, you will find the paper below interesting: we have tested the most popular material for EAP applications.

blast in deep water
Dear all,
I am proud to present to i-mechanicians some recent work by my student Andreas Schiffer. We provide a new experimental technique and detailed analytical models to explore one-dimensional underwater blast problems in deep water.

How to use the C3D27 element?
Hello, everyone!
I want to use c3d27 element to build my model in ABAQUS. But what is disappointed is that one can only assign c3d20 element in the CAE. From the documentation, we can know that, the c3d27 element may comprised of 21 to 27 nodes. So we can make use of c3d20 element to define c3d27 element. However, it's boring to add at least one node to the element. Is there anyone who can give me some suggestion? Thank you in advance.

error in lsprepost file
Hi there,
I'm using LS-DYNA as a tool in my study. Currently, i'm facing this problem:
Run-time check failure#3 - the variable 'count_ntime' is being used without being initialized
Please...help me...I've done so many new models, yet the same error keep occurring...
Thanks...
p/s: i can be reached by this e-mail: man [at] ppinang.uitm.edu.my
about applying load using subroutine in ABAQUS
In CAE, we can apply the concretrated force on a picked node. However, if we want to use
subroutine to difine a complicated force, such as moving load, then we must refer to the COORDS of a point. Because we can use the COORDS of integration points other than nodes, then how to transfer the node load to the integration points load? Any information will be appreciated.
