Concrete Damage Plasticity

Submitted by Velmurugan on

Hi friends,

can you help me in modellingComposite Column using steel and Concrete.

I am using Concrete Damage Plasticity material model for concrete.

I collected parameters from literatures and i tried to implement it into abaqus.

But I am not able to solve this problem.

Abaqus ends the problem with error 

 

Thanks in advance

ABAQUS CAE can not find the time step

Submitted by ABAqirl on

Dear All,

Because i am absolutely new in ABAQUS CAE, i have some problem.

I have created my first model with ABAQUS CAE and the problem which i force,- i don't see the option where i should put the time , So my simulations have only one point. Have anybody has the same problem.

You kind help will be highly appreciated.

problem using crystal plasticity model in Abaqus via UMAT

Submitted by shapoor on

I am trying to model polycrystal behaviour using Abaqus Umat via crytalplasticity . My Umat results for single crystal & about 5 grain, are reasonable, but when, I try to use more than 5 grain in each integration point  (polycrystal model) abaqus aborted with following message after about 15 increment:

Abaqus Error: The executable C:\SIMULIA\Abaqus\6.10-1\exec\standard.exe aborted with system error code 693...

 

I will be happy if someone guide me about this problem.

Post crack behaviour in ANSYS for concrete beam-column connection.

Choose a channel featured in the header of iMechanica

Have a prob in Analysing  FEM discrete model of Beam column connection [both monolithic and precast] for crack behaviour indisplacement controlled cyclic loading program.

 

Tried with various values of closed and open crack and co-efficient. 

applied -1 for crack and changed even the keypoint

in stiffness multiplier also 0.6 also set keypoint 7 to "1" instead of default value "0"

 

But even by all these the analysis runs only for 0.3mm of deflection.. 

 

MODELING COUPLING EFFECTS IN CORD-RUBBER COMPOSITE STRUCTURES

Submitted by saberelarem on

 An analytical model is developed to study the coupling effects in
cord-rubber composite materials. The analytical model takes into account
the mismatch of stiffness between the cords and the rubber matrix
material, and the twist-extension coupling. The transverse deformation,
i.e., normal to the cords direction is based on the normal modes of a
special system which describes the orthotropic and the coupling
behaviour of cord-rubber composites. The equations of motion for the
cord-composite plates are derived using the principle of virtual work.
Results of deformation and stresses are obtained for some typical
cord-rubber composite plates and are compared to the existing solutions.
The results presented illustrate that the coupling effects are
