Arc Length Continuation method fails at low arc length values.

I have implemented a Arc length continuation method for material non-linearity. The program quits with low arc length values while it progresses well for high arc length values. I am attaching a png image for your understating  about the nature of the force deformation curve. Can you please clarify me about the problem and provide me any suggestions on it.

Thanks in advance.

Politecnico di Milano creates a large debate in Italy with its decision to teach only in English

Recently, Politecnico di Milano in Italy has attempted to force all teaching at Master level in English.  This has been stopped by some academics who went to different levels of administrative courts, and recently there was a prononciation of the Supreme Court.  The matter is not settled yet, but you can find an account of this with various links here.

What's the difference between Cohesive Zone Model and Joints Element in discrete element method?

Choose a channel featured in the header of iMechanica: 

Hi,

I am a PhD student working on rock mechanics. I have studied Cohesive Method for a few times. But I am confused on What the special functions the Cohesive element have compared with Discrete method? 

For one DEM software UDEC, model is consisted of solid elements and joints elements. What's the difference between Cohesive element and Goodman element?

Harmonic analysis with a crack?

Choose a channel featured in the header of iMechanica: 

Hello everybody,

                          I am trying to perform a harmonic analysis of a material sample (say a simple 2D plate) with an edge crack in it using 'Ansys R16'. I see that under sinusoidal loading condition, the two crack faces open or close and interpenetrate (after closing which is not possible practically).

          1.  I believe, stiffnesses of the crack faces change during interpenetration and so the results are not credible anymore.

I am new to abaqus and currently working in Abaqus 2016

I am getting the error 5 unconnected regions in abaqus. I have checked thoroughly all the interefaces and boundary conditions but I am not able to sort out this problem. Also I am getting Displacment increment is too big for contact. The job is getting aborted eventually.

I have attached images of the model.

Namaste from India.Jay Naik here. I am Post graduation Student doing Specialization in Machine Design.I am Doing My project in Master in area of" Design of storage tank" in One of the reputed company in Static Equipment Design.Any Idea on which Software(Fea or failure analysis) Design of storage tank is carried out?I have heard about AMETank and Ansys.

Secondly i am carrying out Literature review Present days.reading API 650 and other standards.Suggestion requires in this area.

Please guide me in proper manner.in which way i should carry out the project in systematic way.

Underwater Soil Mechanics Problem

I am an undergraduate student conducting a research project involving the design of a tool to aid astronauts to perform experiments on lunar surfaces and would like to request some direction about which analytical tools would be best suited for this application (i.e. FEA or DEM software/techniques). The specific scenario of interest is to design a tool that can act as an anchor in a sand-like medium (regolith) on the surface of the moon.

defining a time dependent elastic modulus

Choose a channel featured in the header of iMechanica: 

Hi,

I'm working on a model with Abaqus and I face a problem. One of my materials has an elastic modulus which isn't constant according to time. As I search I found out that this should be done by USDFLD subroutine. I'm not familiar with subroutins and how to write them and all the resourses that I've found just confused me more. I would be grateful if someone helps me.....

Hybrid Films to Human Skin: The Relationship between Structure, Processing and Function

presented by Professor Reinhold H. Dauskardt (Stanford University), on Tue, 12 July 2016, 3:00pm – 4:00pm Singapore Time, SUTD Lecture Theatre 1 (1.102).
  

Newton Raphson for FEM

Choose a channel featured in the header of iMechanica: 

Hi,

I am currently working on a FEM  2d plane strain elastic model in matlab. The next step would be to use a non linear constiutive law (Mohr-Coulomb). As far as I have been reading non linearities, are solved with iteration schemes. My question is how to compute the tangent matrix with the N.Raphson method? I have seen only case for polynomials, but not for matrices.

Regards!

Anna
