Development of a Biofidelic Human Head Model from MRI data

Submitted by Simpleware on Mon, 03/16/2015 - 14:39

Traumatic brain injuries from head impact are a major issue across areas such as defence, automotive and sports, and can be costly to research using experimental testing. These injuries can be explored, though, through 3D models created from scan data and computer simulations.

simulation of large rotations by laminated theory?

Submitted by r_n_s_s on Sun, 03/15/2015 - 20:48

Hello iMechanica,

I am wondering if it is possible to perform the non-linear analyses (including large rotations) by laminated theories such as First order Shear Deformation Theory (FSDT) or higher orders and so on. Normally, those theories are valid for moderate rotations but: does anybody know if there is any modification to extend it for large rotations?

Thanks in advance for any advice!

Mesh Update in ANSYS Workbench After Simulation

Submitted by PRITI YADAV on Fri, 03/13/2015 - 22:25

research

Hello Everyone,
I am using ANSYS Workbench (Static Structural). I need to update the coordinates of the nodes, after each simulation.The new coordinate conditionally depends on the stress tensor value of the previous simulation. If anyone have idea how can I solve this problem please help me out....

Thanks!

Ionic Cable

Submitted by _canhuiyang on Thu, 03/12/2015 - 03:42

This paper demonstrates a new type of interconnects to fulfill the primary function of axons: transmitting electrical signals over long distances and at high speeds. The interconnect, which we call "ionic cable", uses ions to transmit signals, and is built entirely with soft, elastic materials-elastomers and gels. The ionic cable is highly transparent, and remains functioning after being stretched nearly eight times its original length. We describe the design, theory and experiment of the ionic cable.

Abaqus cae

Hi everybody,

I want to model a biological cell, diameter of 10 microns! Then what should be the apporx. size in CAE? I am confused! I got to know that the minimum size of parts should be in mm, is this right. then how to solve the problem.

Thanks in advance

rate-state dependent friction in ANSYS

rate-state dependent friction

Dear collegues

a quick question:- I am playing with continuum models of Contact (Hertz, Westergaard and so on) and friction laws. However, I prefer for my students to use ANSYS FEM code. In Ansys there is standard Coulomb, rate-dependence but not rate-state (unless one codes some user subroutines). See

Enforcing tie constraint

Submitted by bfa on Wed, 03/04/2015 - 15:02

Dear iMechanica users,

I have a problem which I would appreciate any input on how to solve. I have an indentation problem, in which I indent a cell with an enclosing membrane. Therefore, I create contact between the (rigid) indenter and membrane, and tie the membrane and intracellular solid elements together. The model is an axisymmetric model, with CAX3 and CAX4R making up the intracellular axisymmetric solid elements and SAX1 the axisymmetric membrane.
