problem with creep analysis using abaqus

Submitted by lamjuv on

hello everybody

when i am trying to make a creep analysis using abaqus and it is the first time i do that

when i submit the job, there is an error and a message appear this message is:

 

 

ERROR: DEGREE OF FREEDOM 11 AND AT LEAST ONE OF DEGREES OF FREEDOM 1 THRU 6 

           MUST BE ACTIVE IN THE MODEL FOR *COUPLED TEMP-DISP. CHECK THE 

           PROCEDURE AND ELEMENT TYPES USED IN THIS MODEL.

PhD position available in computational multiscale modeling of engineering materials

Submitted by Zhiqiang Wang on

A PhD position is available in the area of computational multiscale modeling of engineering materials in the Department of Materials Science and Engineering in the College of Engineering at University of North Texas (UNT). Financial support will be provided through research assistantship. The student will participate in research activities to study material defects, microstructure evolution, and mechanical behavior of crystalline metals, alloys, and nano-composites for a wide range of important applications in areas such as energy and aerospace.

Why we start from honeycombs rather than cocoons.

Submitted by Jin MZ on

The study of cellular solids is greatly influenced by the honeycomb. However, the honeycomb is not a component as whole for bees. Instead, the bee only care the shape and mechanical property of the cells, but in the engineering field, a cell of honeycomb is seldom used. We use them as plate, shell and so on. I think we ignore another porous material called cocoons, the protection to the most fragile period of insects. It is always bearing the load as a whole component.

Abaqus, element removal

Submitted by Hossein on

Hi everybody,

 is there anyone who is familiar with element deletion or removal to predict crackopening in RC member model in ABAQUS?

I've made a 2D model of RC beam in abaquse with brittle cack properties and brittle failure but I could not get any result. Can I make my model by concrete damage plasticity and using abaqus standard to apply element removal?

I will really appreciate anyone who helps me to solve my problem.

 Thanks in advance

Dynamics of AFM cantilevers

Submitted by venapa on

Hi everyone,

I am looking for papers on the dynamics of AFM cantilevers in contact with non linear material samples. In particular, I am interested in forced armonic vibrations of the catinlevers.

I have seen many papers on intermittent contact (or tapping) which has a number of additional problems w.r.t. the contact mode.

Many thanks for the help.

Element remoal

Submitted by Hossein on

Hi

I am intending to make a concrete member model to investigate crack opening in tension zone. First, I wanted to use crack propagation model and could not get good result. So, I think that I can do it by using stress/strain principal failure and element removal.

I've tried to fiure out how I can apply this method in my model.

Is there enyone who has experience in this issue? Could you please help me in this matter?
