designing a diaphragm
I am designing a diaphragm for shock tube, I need formulation to calculate the thickness of the diaphragm for rupture pressure, I intend to use thin aluminium foil as a diaphragm. Can I use thin-wall theory? σ=pr/t

I NEED HELP IN ANSYS ELECRTOMECHANICAL COU[PLING FOR SMART MATERIALS
Hi,I'm new to ANSYS. i'm working on project of active vibration control using piezoelectric patches using ANSYS .
But i'm finding it difficult in modeling of piezoelectric actuators and the input data required for it(VOLTAGE AND MATRIX).
Can any1 help me?i will be thankful

i m trying to do thermal analysis of rapid manufacturing process called LENS in abaqus(64-bit). Based on thermal results(thermal odb), i m doing a stress analysis. In order to complete a 90 step analysis along with DFLUX subroutine using quadritic (DC3D20) elements (approx 30000 elements), it takes nearly 30 hours(intel core i-7 processor and 6Gb of RAM) and more than 7 days to complete stress analysis. 13-14% of the CPU usage is observed duing stress analysis. is there any way to enhance the performance??
Coupled Temperature Displacement Analysis for layered Soild
I am trying to carry out coupled temperature displacement analysis for layered solid in ABAQUS 6.8 but it is not accepting coupled temperature displacement type element for layered solid (Composite). I would like to request for some suggestions/ way out to carry out the same in ABAQUS.
Thank you.

What we call Robust Design Optimization (IOSO RDO Application example)
Nowadays there are many technologies that people call Robust Design Optimization. Among them one can encounter for example such popular methods like six-sigma. But despite the absence of common terminology for RDO, one can agree that methods and technologies like six-sigma may be called as sensitivity analysis other than Robust Design Optimization. Real-life RDO technologies could be classified by the deepness and thoroughness of the development of their theory and their practical realization.

Hi All,
I am into machining simulation of 50CrMo4 Steel in DEFORM 3D and I need the flow stress curve data for various temperature and various strain rates. I have searched in as many journals as possible, but in vain. It would be of immense help if some one could share the material model data with me.
Thanking you in advance
With Best Regards

strain components in plasticity analyses using abaqus
Forums
Choose a channel featured in the header of iMechanica
I have recently been obtaining strain components using abaqus when modelling metal plasticity problems (large deformation/strain, 3D model using C3D8R elements) and accepting the strain components as supplied in the output. A colleague has questioned the validity of such components (i.e. integrating strain rate to get strain) when the principal axes rotate, which is inevitable in the type of deformation I am modelling. I had assumed the co-rotational formulation in Abaqus would take care of this. Any comments would be welcome.
How is this possible in ABAQUS?
I am trying to run UHYPER in ABAQUS 6.9EF1. I have the following questions:
1) How can I get the nodes
ID associated with element# NOEL in UHYPER subroutine?
2) How can I get the
coordinates of the displaced nodes associated with element# NOEL in UHYPER
subroutine in the middle of the simulation? I tried to use GETVRN but it seems it does not work in
UHYPER.
Run ANSYS through MATLAB
Hello All,
Does anyone know if it is possible to run ANSYS as a solver through MATLAB ? I want to run optimization in MATLAB and change some variables whether they are geometry or material variables and run ANSYS through MATLAB to solve especially ANSYS CFX or Workbench where I can have multiphysics.
If this is possible, I would appreciate it if you can share the method of how to do so.
Thank you all
