Reinforced Concrete in ANSYS

I am conducting a senior design project in ANSYS.  I am modeling a folded reinforced concrete plate and have never used ansys before.  Does anyone have any tutorials that involve non-linear analysis?  I am trying to get a force vs. deflection curve and I am having troubles.

 Thanks

Career after the Ph.D.

Hi,

I'm an Engineer and a Ph.D. student in Applied Maths, working in the field of Nonlinear Finite Elements for Elasticity. I often think about my future career since, by now, I have a strong experience with coding FE in C++/Matlab/Mathematica, but no clue whatsoever about commercial black-box softwares for FEA. I'm worried about this, since most of the job vacancies from the industry (I'm not interested in pursuing the Academic career) seem to require only experience with a specific software and application, and not to directly code FE.

Beam - Simply Supported - Quad8s

Example of 8-node shell elements representing a simply supported beam.  The beam can represented in two different orientations.  Both are equivalent if the plate thickness is the same as the length in this case.  The boundary conditions in the upper beam actually depend on how the beam is physically supported (whether the restraint is underneath the beam or in the middle or at the top).  In this example, I have placed the support in the middle.  Restraints have been added in the X and Y directions on one end and in the X direction on the other end.

FEA Improves Reliability of Flip-Chip Packaging

On Aug 10, 2009, Semiconductor International (SI) Newsbreak published a report on my work in AMD about 3D fracture study of underfill delamination as the top story in that issue.  I have never imagined that. Except the pleasure I received from this good news, I wonder if this work is also interesting to iMechanica community.  For that reason, I attach here the SI news report and the original paper published on ITherm2008 Proceedings. Welcome any comments and thoughts.

 

Reg. Penetrations in a Contact Analysis Code

Choose a channel featured in the header of iMechanica: 

Hi,

 

I have developed a FORTRAN code to simulate the molding process of glass to make lenses. Hence, it involves a contact analysis between the glass and molds. The contact is modeled using the master and slave node concept and the mold is assumed to be rigid. For the application of this code, we are looking at highly precise dimensions to capture the curve of the mold on the glass after molding.

Compressive Strength of Fabric??

Choose a channel featured in the header of iMechanica: 

I am trying to model a rubber impregnated fabric as rebar in Abaqus Standard. It seems that the rebar is only good in uniaxial tension load and it causes convergence problem in bending and compression loading. The fabric and rubber matrix has a compressive strength and that is critical to the model that I am analyzing. What would be a good approach to include compression on fabric rebar? The compressive strength of fabric matrix should be an order of magnitude lower than the tensile strength but I do not have a test data in compressive loading.

Modelling Hyper-elastic Plate Using ABAQUS

Dear All,

For months, I have tried to model a plate with circular hole which has the properties of hyper-elastic material (Ogden) but the results are still not promising compared to literature (Y Basar 1998).  The main problems are:

1. The maximum load I succeeded to apply was q=26, while literature had applied load up to 90. For q > 26, the analysis will terminate with errors such as too many attempt, excessive distortion etc.

2. The results I get for q<26 are not the same as literature. 

I attach my best result for your viewing.

Nominal stress Vs Nominal strain plot in FE simulations

Hi all,

 I want to plot nominal stress Vs nominal strain plot from my FEA simulation. In generally I will get stress and strain at element level, now how can I plot stress-strain for the overall struture. I am applying uniaxual load on specimen. My analysis is non-linear.

Thank you

Regards

Gouse

 

Producing Stress Analysis from Strain data

Choose a channel featured in the header of iMechanica: 

I am doing research on the stresses that are produced when a retainer (a thermoplastic sheet) is placed on the teeth. We've designed the project so that we take an initial scan of the sheet and a final "shifted" scan of the sheet. We'd like to compare, find the strain, and calculate the stress neccessary to produce this strain.

I was hoping to use FEA for this...is it possible? I have access to Abaqus and Ansys, and where can i find the commands that allow me to do this.

difficulties CONTACT problem with plasticity using ABAQUS FEA code.

Hello everyone:

1.  I have built a FEM model 2D plane strain using ABAQUS/Standard (CPE4R) elements,

2. I am  modeling the contact between a cylinder and a plate in 2D.

3. The Cylinder material is given is ELASTIC ISOTROPIC material with no plasticit E=310 GPa

4.  The plate is with a Ramberg-Osgood plasticity with a Young's modulus E=210 GPa.

5. The mesh at the the contact point is VERY refined element characteristic length is about 1 micron. (My model units are  (mm,N,sec)).
