problem related with full integration

Submitted by yihit on

Hi,

I am new to ABAQUS and have met a problem in input file. If I set the element type to be CPE4R, the input file works perfectly. However, CPE4R has only one integration point, which is not enough for my problem. When I define the elment to be CPE4 in the input file and set section control to be hourglass, the computation is terminated with error in input file. I don't konw what's the problem here. Could anyone help me with the problem?

Any information is appreciated.

Can I input variable piezoelectric properties to UMAT subroutine and do coupled piezoelectric analysis?

Submitted by Linhui Zhang on

Hello,

 I am using abaqus to do research on polarization procedure of piezoelectric materials. I want to develop a user subroutine that can allow me to input variable piezoeletric material properties and do coupled problem. I want to know if UMAT can solve this problem or I need to use other subroutine. If there is that subroutine, what is it.  Any suggestion is appreciated.

 Thanks in advance,

Linhui Zhang

Modeling Reinforced Concrete Element in Abaqus Standard

Submitted by looyong on

hello everyone,

I am trying to model a concrete element subjected to static load using Abaqus Standard. For concrete, I am using Concrete Damaged Plasticity and beam elements for my reinforcement. I am embedding my reinforcement into the concrete (host elements).

Since I started, I faced several issues. They are overconstraint, numerical singularity and negative eigen values. I managed to resolve both of them. However, the behavior from my model is nowhere near the experimental data that I have. It seems that the model is excessively stiff.

free vibration mode shapes of beam (other than pinned-pinned) and finite strip method

Hi everyone.

I'm working on my master thesis, dynamic analysis of plates using finite strip method.

I have found one problem (among others) that could be interesting to community.

In the attachment you can find example from Mathematica. There is 21 mode shapes of clamped-clamped beam. Recently i noticed that formulation given in every book about dynamics (Timoshenko, for example) isn't valid for higher modes for any beam that isn't pinned on both ends.
