Needle Insertion Into Soft Tissue

Choose a channel featured in the header of iMechanica: 

I'm modelling the deformation of a soft tissue under needle insertion, but I'm having difficulties because the data I have is not sufficient. What I need is about the epidural space, elasticity constants, inner and outer radii, etc. Can anyone give me some answers about that.

New Master's program "DESIGN des MATÉRIAUX et des STRUCTURES" at MINES ParisTech (in French)

The Centre for Material Sciences (MINES ParisTech) opens a new master program (450h of courses + internship in the industry). The majority of courses are tought in French, so this program might interest french students finishing their master courses this summer (2015) or french-speaking foreign students holding a degree equivalent to the french master. We are looking for motivated candidates!

A state of stress is a linear map

A state of stress in a body.  Components of stress.  Subject to a load, a body develops internal forces.  The distribution of the internal forces in the body is usually inhomogeneous. For example, when a rod is bent, part of the rod is in tension, and the other part of the rod is in compression.

If the internal forces are uniformly distributed in the body, the body is said to be in a homogeneous state of stress.  For brevity, we often say a state of stress, or just stress.

How to implement GTN Damge Model in Abaqus

Dear Friends,

 

                      I have to know how to implement a GTN Damage model in Abaqus. Is there any Examples or Tutorials to learn this technique. Can anyone possible to solve my problem.

 

I trying implement this Damage model for the axisymmetric Model. I have uploaded for your reference.

flexural vibration beam+ponctual mass

Choose a channel featured in the header of iMechanica: 

Hello everyone,

I  modelled  a slender beam (an Euler-Bernoulli beam)  in flexural vibration in Abaqus  in order to do a natrural frequencies extraction. And, then i wanned to analyse the impact of a concentrated mass in its end. but for the first mode, i obtained a result understandable but not for the following modes which i verified analytically. the viewport of this fundamental mode can be found as a file attachement.

Could you please give me an explanation. And Thank you very much for your help

How to define initial stiffness matrix for cohesive elements in ABAQUS

I am trying to  model adhesive failure using cohesive elements in Abaqus. I need to define the elastic behaviour of elements using traction separation criteria.

So I wanted to know what is the E/Enn, G1/Ess and G2/Ett values for my adhesive(E=1650 MPa)?

Essential parameter/properties masonry structure modelling (ABAQUS)

hai, im haidar (undergraduate-civil engineering from Malaysia)

Kindly please help me, 

currently im working on my thesis which majorly focused on the dynamic analysis of masonry (Concrete Masonry Unit) multistorey building structure,

presently, im modelling the 3 story building (including ground floor) of masonry building with block size of (200x400mm) including 10mm thickness of mortar joint

(macro-modelling) using the ABAQUS program. However, im facing few issues and confusion regarding on masonry modelling:

 

analysis Composite at Abaqus

Hi every one

I try to analysis my Model at Abaqus. I want to use continume shell model to create the composite layer. The model shape is so complex and I can not use Hex meshing. Abaqus just meshing the model as Tetra element. And my problem is abaqus do not accept tetra az composite layer at element type. I try to daturm the model very smal part until may be can define hex element but its not work. There is any way I can use tetra meshing for continume shell.  

How to convert ls-Dyna to Abaqus file.

Choose a channel featured in the header of iMechanica: 

Hi,

I am doing a project on the effect of forming in fatigue analysis of a component.I have .key file from dyna which I have to run analysis in abaqus. I need to carry the dyna output containing initial stress and nodal thickness into abaqus and carry analysis which I currently am not able to do it. Kindly suggest me how I can do that if u know.

TECPLOT

Choose a channel featured in the header of iMechanica: 

How to plot multi contours in tecplot at a time from two different files.

for example i have two different excel data files A & B with node coordinate and its mises value. I  knew how to plot the individual contour in Tec plot using individual files A & B but now i want to plot both the contour on same page using these individual files (A+B). So, anyone can help me......
