I build a water inject model with COH3D8RP element, in the simulation, I can get the pore pressure value around the cohesive element, but I can't the value inside the cohesive element. the pore pressure changed around the cohesive element because of the pressure inside the cohesive element changes, however, I can't get the value of pressure inside the cohesive element.
Hi FEA analysts
Could anyone please explain how to extract force for displacement method
in FEanalysis using hypermesh preprocessor, lsprepost and lsdyna solver
Managing risk can be effectively done with the right software tools. Specifically with enterprise risk management software tools. In mechanical engineering projects, managing such risk is paramount to success and meeting deadlines. Most mechanical engineering students will not study such processes, but in having knowledge of managing risk, you will put yourself on a higher pedestal.
In this study, using a UDMGINI subroutine, stress components relative to a predefined osteon orientation were computed and an anisotropic damage criterion was used to determine damage initiation and to predict crack propagation.
I am trying to find out if someone has information about the "embedded region" constraint in Abaqus. I am trying to model a very simple short fiber in a matrix (short cylinder inside a block). The model is purely elastic. The problem is, no matter how high I assign the values of the E modulus of fiber, I always get equivalent properties of composite (fiber + matrix) equal to matrix properties.
I was wondering if you have any idea that how can I define the surface-to-surface interaction betwee axisymmetric shell element(SAX1) and soil element(CAX4p).
This Technology Brief describes Abaqus/Explicit
modeling of the ballistic impact of metal projectiles on metal targets.
It will demonstrate the utility of Abaqus/Explicit as a tool for
reducing the amount of experimental testing as well as assessing the
projectile residual velocities and time-resolved kinematics.
I'm a freshman in biomechanic and apply to learn user subroutines in ABAQUS by FORTRAN.
I have installed the ABAQUS 6.11, VS2008 and IVF 11.1.
But I don't know how to call the subroutines in ABAQUS, so I will be very appreciate if someone give me some suggestion or simple tutorials about this.
I want to model a soil body which its shear modulus changes with the deviatoric strain.I know it can be introduced in ABAQUS by field variables (defining a field variable). But the question is that how can I tell ABAQUS that the defined variable is the "deviatoric strain" ?
While post processing in hypermesh ,we can use either contour or assign. i need to know difference between this and which is the best to choose for viwing the results.
I am an Aerospace Engineer working at Advanced Composite Division of National Aerospace Laboratory, Bangalore.
I use Abaqus for stress analysis of composite structures.
Abaqus has five inbuilt failure
criteria for composite materials(Tsai-Hill, Tsai-WU etc.) whose contour
plots are shown by requesting output of a field variable called
CFAILURE.
I would like to calculate maxim safe size of delamination in composites using ansys/abacus.
I went through the forums here found that cohesive zone modeling & vcct techniques are being used only in ABACUS. Is it not possible in ANSYS APDL?
If not please can somebody provide me tutorial of ABACUS regarding interfacial cracks. Also which one better VCCT or Cohesive zone modeling for an existing crack.
I use ADINA. After my static analysis, I plot bending moment distribution over a cross section. Is there a way to find total bending moment at that section in ADINA software? I think some integration is required to do that, but have no idea how to manage it with the software. Surely, there are similar operations in ANSYS, ABAQUS etc.
I just posted a Matlab-GUI easy-to-use DIC and DVC simulator tool on our website (franck.engin.brown.edu) for download for anyone that works with DIC or DVC. The purpose of these simulators is to simulate deformation fields based on a user provided image (2D) or volume (3D), and evaluate the correlation results with the analytical solutions to provide quantitative feedback on the "goodness" of the provided images for DIC or DVC purposes.
Feel free to use them for research, teaching, etc. We welcome any suggestions for improvements, etc.
I am a graduate student in Hunan Univ, my research field is meshless method. Instead of using codes to calculate, I find EFG has been well developed in ls-dyna, and using software may be more convienient for me.
But I can only find some introductional information, so I want to find some useful material in iMechnica.com!
