2D Mooney Rivlin Strain Energy Function

mooney rivlin

Hi,

I want to model a tissue using the Mooney Rivlin strain energy function. However, I am currently working in 2D (plane stress or plane strain would do). I only found the 3D material model for the strain energy density function online. What modifications should I make for converting it to 2d? I read that there is only 1 parameter required for the 2D case as opposed to the 3D case. What is the equation of this function? Is there any relation between the parameter C10 and C01 of the 3D case, and C1 of the 2D case for the same material?

error

Hi colleague

does anybody know, what is this strange error : Error in connection to analysis

i am trying to model fracture mechanics on piezoelecteric material, when i select the piezoelectric as a familiy in mesh part, then when runing the model, i recieve this error. if anybody knows how to fix it please help me.thanks

Fractal surface mesh generation

Fractal

Saber El Arem (node/14053 ) wanted to know how a fractal surface mesh could be created.

I've had to do that in the past. What I did was to use Arjun Viswanathan's 1999 Matlab snippet on creating a plasma fractal and write a wrapper around it to create an output file that could be read by the then available version of Abaqus.

I've attached a couple of Matlab files that should be able to do the job. The .txt extensions are needed because iMechanica does not accept files with .m extensions.
