On efficient finite element assembly in Matlab

As we all know, finite element matrices are sparse and many memory can be saved if their sparsity is exploited. Due to the latter, we are often provoked to declare the nxn stiffness matrix as a sparse one just before the element loop. Be careful of this method since the larger the matrix the slower the assembly operations. There is a better and more efficient way to code the assembly procedure in Matlab. I will show how to accomplish this.

how to active adaptive mesh option in ADINA System?

hello to every body ;)

  Iam hasani- gradute student

I'm new user in adina. i worked by ansys and abaqus for several projects.

in adina  when i choose control>solution process...>adaptive meshing> full the program return it to none!.

i tried to understand about the reason. but in fact i can not find the problem.

i think in program , there are some constraints that should be change before the full adaptive meshing.

please help to find the problem. thanks

Load-displacement curve in ABAQUS

Hi all

 I want to derive a load-displacement curve for a compoaite laminate shell which is subjected to a uniform displacement field in ABAQUS. The problem is somehow similar to example 1.1.14.

I have derived the data for Reaction force of each node and also for the Us. The curve for the maximum node is plotted but the data are half of the values reported in Example 1.1.14. I don't know what's wrong with it. Please help me with this problem.

Download your Free Abaqus SE

Download your Free Abaqus SE at: http://campus.3ds.com/simulia/freese

SIMULIA Academic programs would like to offer you a complimentary copy of our Abaqus SE (student edition). Now students can have their own personal finite element analysis tool to use on or away from campus. Abaqus Student edition is ideal for students using Abaqus as part of their coursework as well as for practicing engineers who wish to become more proficient with Abaqus.

contact problem

hi all,

my name is christian, i'm a master degree student in mechanical engineering. i've been doing a swaging  process simulation using MSC.MARC, but i have a problem.when i ran the simulation, there were some node or element that penetrated into the other element and/or rigid body. i tried to change the value of contact tolerance and mesh, but i got the same result (pentrated still happened). what should i do to solve this problem?should i use mesh adaptivity? please help me ^^

Applications of Fracture Mechanics

These notes were prepared when I taught fracture mechanics in 2010, and were updated when I taught the course again in 2014.

Notes on other parts of the course are also online.

How to import a matlab cuve into COMSOL for further constructing geometry model?

I created a curve (1D) by matlab. then i want to import it to COMSOL, and based on it for further constructing geometric model. does anyone know how to import this curve to COMSOL?

P.S. I used COMSOL3.5a with MATLAB. 

 Thanks.

Viscoelastic material model in abaqus-am i taking the correvt approach

Hi all,

I have been trying to gain an understanding of representing a viscoelastic material in abaqus. To do this i have been trying to represent polypropylene using data obtained from creep curves found in literature (attached). To now what i have been doing is the following: Note i am using Abaqus 6.7

In material manager: selecting Elastic-inputting Instantaneous Youngs Modulus, E, Poissons, v, (E=1.8GPa, v=0.4) and setting the moduli time scale to instantaneous. And Viscoelastic-Domain:Time, Time=Creep Test data and inputting Shear Test Data

New idea in fatigue problems

there are two analytical concepts that are very important in fatigue failure.the first one is crack closure and the others is residual stress .the first one is in behind of crack and the other emphasis in the front of crack tip. the question is if we use some devices such as AFM/SEM is it possible we model the energy filed during fatigue process?   if this idea can be investigated the second question can be asked: is there any similarity to model for different loading conditions? 

 

I appreciate if you also put your comment in my idea?

 

Bes Regards,
