Hello everyone,

The Interdisciplinary Centre for Advanced Materials Simulation (ICAMS) is a new research centre at the 
Ruhr­University Bochum, Germany. At ICAMS an interdisciplinary team of scientists from engineering, 
materials science, chemistry, physics and mathematics is working on the development and application 
of a new generation of simulation tools for multi­scale materials modelling. 

Hello,

I am a Masters student and I need to model a spring shape memory alloy in ABAQUS. I have found a UMAT file,however the file contains the geometry of a 1X1X1 cube. Does anyone have any idea of how I could copy the geometry of the spring(which i modeled in solidworks and imported to ABAQUS)into the input file of the cube,so that I could run the model in ABAQUS. I have tried this but ABAQUS is giving me errors

Or does anyone have any other idea of how I could model a Sping SMA in ABAQUS?

Thanks

Akin

Hi,

I'm looking to solve a problem in which although the position of a boundary or force-generating constraint is not known, the distance between the constraint and one other (usually a "neighbouring" particle -- whatever neighbour means ;) ) is known.

After much thought, I've concluded that the problem is a constrained energy-minimization problem. In other words, I need to find the arrangment of the particles such that the strain energy of the system is minimized and while constraint between the nodes is satisfied.

I'd like to know if (1) this is the proper approach to the problem (2) there are any publications addressing such problems.

Thanks

I'm looking for the thermo-mechanical properties of aluminum, such as  Young modulus, thermal expansion coefficient, thermal conductivity coefficient and poisson ratio as a function of temperature :

E=E0(1+E1*T+E2*T^2+E3*T^3)  ;  T: temperature in K

Hello.

I am new in both iMechanica and ABAQUS and I would need help:

Postdoctoral and Graduate Assistant Positions are

The Catholic University of America (Washington DC) invites applications for a Ph.D. studentship. The focus is on the development, and eventual incorporation into existing Database Assisted Design (DAD) software, of novel schemes allowing for the efficient optimization of tall buildings subjected to wind loads. This work forms part of an existing effort between faculty from the Catholic University of America and the University of Maryland-Baltimore County, as well as researchers at the National Institute of Standards and Technology (NIST).

Hi friends,

Can you explain Baushinger effect?

how it is related with KINEMATIC HARDENING?

Thank you

Hi all, I am a new ABAQUS VUMAT user. I am defining the material behavior in stamping of sheet metal through VUMAT. But there are several questions about VUMAT.

（1）accoring to the ABAQUS user manual，for plane stress problem，stressnew(nblock,ndir+nshr), where ndir=3,nshr=1, but in fact,there are 5 stress commponents: sigma_{11},sigma_{22},sigma_{12},sigma_{23},sigma_{31}.

how to match stressnew(*,i)(i=1,2,3,4) with the stress commponents: sigma_{11},sigma_{22},sigma_{12},sigma_{23},sigma_{31}?

Hi all ... can somebody suggest me good book(s) on plate/beam theroy? The book should start for a novice and should go till large deformation part. Step by step explanation atleast for first few chapters should be there. Thank you.

Hello, I am trying to model a steel beam subjected to elevated temperatures using the ISO834 curve.

Dear all,

can anyone direct me to litrature in which modelling the diffusion equation of fluid porous flow is unified with the free fluid flow. I mean that the porous media is considered deformable and equilibrium conditions are solved simultanouesly with diffusion eq. for porous flow and at the same time fluid velocities inside and outside porous media are linked together in a poroelastoplatic framework; where porosity and geometry are updated with each time step!

Thank you in advance!

Recently I have some reseach on z-pinned composite. I hope use finite element method to analyse the unit cell . I found a FE code called FLASH mentioned in many papers. I think the code will be helpful to my work.But I can not got the code form my resource. So,I ask help in the forum. Two papers about the code are given in below. I am very expect for your help!!!

Hello,

I would like to develop a Program for finding the Stiffness of a stabilizer bar using FE methods.

I have a fairly good idea about FE methods as to how to proceed but the books i referred to mostly dealt with symmetric solids.

Can someone throw light on FE procedure for such component with a complicated shape(or some books that deal with 3D assymmetric solids)..??

Thanks.

I am  searching the paper "Evaluation of stress distribution in the symmetrical neck of flat tensile bars" of J. Aronofsky published at Journal of Applied Mechanics (1951).

The publisher sent me the other day this new book by Audoly and Pomeau.  I haven’t gone through the book carefully, but a quick look has indicated that this is a very special book, well worth a close reading.  The book is beautifully written and well produced.  The authors have captured the recent excitement about thin elastic objects, such as rods, plates, and shells.  While existing books on plates and shells mostly focus on calculating critical loads for instability, this new book describes shapes produced by instability.  Examples include wrinkles in a leaf, ridges in a piece of crumpled paper, and curls of a hair.  The subject is photogenic, and the book contains a large number of delightful illustrations.  The book approaches the subject through physical phenomena, rather than mathematical formalisms.  The authors have intended it as a text for a course at the level of senior undergraduate students or beginning graduate students.         

Dear All,
I would like to announce a symposium in memory of Pr. Olivier Coussy

Mechanics and Physics of Porous Solids : a tribute to Pr. Olivier Coussy

It will be held at Ecole des Ponts ParisTech, France from 18 to 20 April 2011.

Hello!

Let's discuss here some subjects related to Fractal Fracture Mechanics and Fracture Thermodynamics,

Dear all

I am looking for some papers about hygrothermal effect in composite plates.

some of these are here:

I am going to study the diaphragm behaviour of the composite slab (PSSDB system) under the lateral loading. the PSSDB system comprise of profiled steel sheeting and dry board that are attached by screws. Concrete could be used as a infill material to improve the insulation of the system. having the concrete would improve the structural behaviour of the system.

I am going to simulate the system using FEM package (such as ANSYS or ABAQUS). the obtained results from FEM package would then be verified by experimental results that must be done by myself.

I need your help to know how to model the system in FEM.
