Viscous Regularization

Submitted by Navid Moheb on

Hello everyone,

I am working with Abaqus and trying to model a problem using pore-pressure cohesive elements but I have a hard time on the converging side of it. I was looking at the articles and Abaqus Documentation and I found viscous regularization az a method to help. Actually I found the papers that firstly introduced this method but I cannot get it very well and I was looking forward to see if anyone can help.

simulation of large rotations by laminated theory?

Submitted by r_n_s_s on

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

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!

PhD Robust Optimization Viscoelastic Sandwiches

Submitted by Hamdaoui on
Visco-elastic structures are widely employed for vibration damping. Nowadays, optimal design of these structures has become commonplace. However, operating conditions introduce variability in their performances. Taking into account this variability in the optimization loop is necessary to obtain optimal robust solutions. Recently, within an exploratory project, supported by CNRS, the modal stability method (MSP) has been applied with success to quantify variability of damping and natural frequency of frequency dependent viscoelastic sandwich structures.

Ionic Cable

Submitted by _canhuiyang on

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.
