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.

Dear all,
I want to construct a constitutive relation to model the elastoplastic damage behavior of rock salt which is considered as an excellent host medium for gas storage facilities. Because rock salt is a kind of typical geomaterials, confinement sensitive and inclusion effect should be considered in the constitutive model. However, I have encountered many difficulties in the course of the study. There are some issues I am a little confused.
