This study concerns simulation of the forming process of a carton-based package for liquid food (for example, milk or juice), and how the packaging material interacts with the fluid during the forming. The carton-based package is formed inside a filling machine while the fluid is being filled into the package. The carton-based package is thin with low bending stiffness and is thus deformed significantly at small loading. This implies that the forming of the package to a large extent depends on the dynamics of the fluid inside the package.

From a structural point of view, corrugated board would fit on the category of sandwich structures, which in sectors as aeronautics or construction are today commonly analysed using simulation tools that are based on the Finite Element Method.

The Virtual Race Track, VRT, suite of simulations is the most recent addition to the automation tools known as Virtual Package Simulation, VPS, for analyzing the performance of plastic bottles. These new simulations predict the dynamic performance of bottles traveling on conveyors. The objective is to determine if the bottles remain standing after impacting fixed guide rails and gates. The bottles must remain standing to be effectively conveyed. By using ABAQUS to predict this performance, designs can be evaluated much earlier in the product development cycle.

This paper presents several modeling techniques for simulating and optimizing

Automation of analysis routines for designing packages has lead to the development of the

Production of glass bottles requires blowing of the glass after entrance of a gob of molten glass in the blank mould. The final shape of the bottle is highly dependent on the viscosity of the glass, the blow-pressure and the temperature distribution in the glass and the mould and simulation of this complicated process enables optimization of the process conditions. During simulation of blowing of the glass, the mesh has to be adapted due to the extreme deformations of the mesh.

Dear All,

I have a beam with a hole under pure bending moment. I am very intrested to know is there any

relationship between the moment in the beam section and the stress concentartion (specially tensile stresses due to moment ) around the hole?

Any help will be highly appreciated,

Thank you,

Manooir

Energy harvesting is the process of converting energy that will otherwise be dissipated into the ambient environment, into useful energy to do work.  I shall focus this discussion on motion-based energy harvesting.  Motion-based energy harvesting is the process of converting dissipated mechanical energy into electrical energy.  Sources of mechanical energy include the ocean waves, wind, human motion, vehicular traffic, and vibrations in buildings and bridges.  This source of energy is ubiquitous and pervasive, and yet, it is one of the least developed energy harvesting technology.

We would like to continue the demonstration of IOSO possibilities. Please take a look at our videos:

1) Metallurgy. Chilling room optimization

2) IOSO - LS-DYNA. Punching out structural optimization.

3) IOSO - Flow-3D. Casting. An HPDC study: optimizing shot sleeve velocity profile.

I am a PhD student on Timber structure.I have modelled timber beam using solid 45 element as 4 points bending but my result is overestimated.I have reviewed the literature and I have found that assigning Tsai_Wu failure mode in timber can solve the problem.I have found Tsai-Wu in following category in Ansys 12.1:Material model/nonlinear/inelastic/non metal plasticity/failure criteria/criteria3But Ansys appears the following error:*** ERROR ***                           CP =       2.891   TIME= 16:56:04

Hi 

 I am working on a project where fracture parameters are to be studied at the interface of a bimaterial body ..I would like your help for the following 

1 .If there is any Material or papers contentrating on the above plz let me know

2 . Which FEA Program gives or works best on this kind of prioblems 

thanks in advance 

Dear all,

i looking for a Fsi modeling in abaqus . anybody can help me?

thanks a lot

I am kind of new in computational simulation except for CFD. I have a cylinder which has a flange around it and a lid on top. Lid and the flange are connected by bolts and sealed with an o ring. Is it possible to simulate the load distribution around the flange due to tightening the bolts? Which package is most suitable for this comsol or Abaqus? I want to do simple simulation just to check whether the odd number of bolts are able to distribute load uniformly around the flange.

Thanks in advance.

Dear all:

I am currently pursuing Master of Technology at Indian Institute of Technology,
Kanpur (India) in Mechanical Engineering department. In my masters thesis I am working on analytical and numerical (FE) analysis of dynamic buckling of thin walled circular cylindrical shells under fluctuating radial pressure. I am expecting to submit my thesis by the end of August, and after that I am planning for a PhD. I want to continue to work on the dynamic analysis of structure for my PhD thesis, and I am looking for a PhD position in some European or Canadian University.

 sir,

    can u pls give the relevelent imformation to  model the composite  structures using fea packages like abaqus and hypermesh
