Toward realization of computational homogenization in practice

Dear all,

I have read the article of Yuan and Jacob Fish entitled "Toward realization of computational homogenization in practice" and realize that they have published the source code they used in their paper. Unfortunately, I cannot download the code from the link that the authors provided. I wonder if any of you have downloaded the code before. If so, please kindly share the code to me.

Thanks in advance.

What could be a challenging issue for renewable energy structural design?

Dear All,

I wonder to know what could be a challenging issue for renewable energy structural design, from solid mechanics point of view? Is there any major problem with structural design and analysis of the renewable energy structures?

Regards,

Localization and instability in sheared granular materials: Role of friction and vibration

Shear banding and stick-slip instabilities have been long observed in sheared granular materials. Yet, their microscopic underpinnings, interdependencies and variability under different loading conditions have not been fully explored. Here, we use a non-equilibrium thermodynamics model, the Shear Transformation Zone theory, to investigate the dynamics of strain localization and its connection to stability of sliding in sheared, dry, granular materials. We consider frictional and frictionless grains as well as presence and absence of acoustic vibrations.

Objective Fracture Parameters and a Paradox for Interface Cracks

Due to the oscillatory singular stress field around a crack tip, interface fracture has some peculiar features. This paper is focused on two of them. One can be reflected by a proposed paradox that geometrically similar structures with interface cracks under similar loadings may have different failure behaviors. The other one is that the existing fracture parameters of the oscillatory singular stress field, such as a complex stress intensity factor, exhibit some nonobjectivity because their phase angle depends on an arbitrarily chosen length.

A note on the pull-off force for a pattern of contacts distributed over a halfspace

ArticleinMeccanica · March 2017 --- We found a very simple formula for pull-off force for a pattern of contacts distributed over an halfspace which could be very useful in predicting the adhesive propreties of structured surfaces, as bioinspired surfaces.

PhD scholarship in Ecole Polytechnique, Paris, France

One Ph.D. position is now available starting October 2017 on harnessing instabilities in magnetorheological elastomers. The PhD will be pursued in the Solid Mechanics Laboratory of Ecole Polytechnique, Paris, France. The potential student will work on the development of new experimental procedures and numerical models for the fabrication and testing of new magnetorheological elastomeric devices that operate in the postbifurcation regime by proper combination of mechanical and magnetic loadings.

Masonry modeling in Abaqus

here we are to tell you how we can model masonry in abaqus cae.
there are 3 ways:
1-micro modeling
2- macro modeling
3- micro-macro modeling(HOMOGENIZATION)
micro modeling; 
in this method all parts should be modeled in abaqus separately.
but notice that don't use shell to modeling grout because of 3d properties of grout and cohesive characteristics.
this method is suitable for small masonry panels with 2-3 layers of brick.

A simple finding on variable amplitude (Gassner) fatigue SN curves obtained using Miner’s rule for unnotched or notched specimen

We provide a very simple result for a problem which has been often neglected (variable amplitude loading) in academia, but which is of paramount importance in real engineering situations, where fatigue is almost never "constant amplitude".

We found few cases where we could check this extremely simple result, but it worked very well.  We would welcome further verifications.

The paper is in press here.

A phononic band gap model for long bridges. The ‘Brabau’ bridge case

In this paper, we study the dynamic flexural behaviour of a long bridge, modelled as an infinite periodic structure. The analysis is applied to the ‘Brabau’ bridge across the river Tirso in Italy. The approach reduces to a spectral problem leading to the analytical expression of the dispersion relation, which provides the ranges of frequencies for which waves do and do not propagate. The contributions of the bridge structural elements on the dispersive properties of the structure are investigated in detail.

Ansys Tutorial

Composite materials are created by combining two or more layered materials, each with different properties. These materials have become a standard for products that are both light and strong. Composites provide enough flexibility so products with complex shapes, such as boat hulls and surfboards, can be easily manufactured. Engineering layered composites involves complex definitions that include numerous layers, materials, thicknesses and orientations. The engineering challenge is to predict how well the finished product will perform under real-world working conditions.
