Delaminated Composite Plate

Choose a channel featured in the header of iMechanica: 

 Hi,

 I am researching delaminated composite plates.

 How can i model the delamination area in two plies, is abaqus a correct choice for modelling?

 Delamination area is rectangular or circular.

 Regards.

Multi time scale simulations for wear prediction in micro-gears

Reliability of micro-gears is known to be adversely affected by wear. In this work we report a strategy to predict local wear with the aim of predicting their effective life span. For the prediction of local wear we start from the relevant model experiments, choice of a suitable wear model and identification of the wear coefficient from these experiments. This wear model is then implemented in an efficient finite element based scheme to predict local wear.

Multiscale Modelling- Introductory Literature

I am looking for introductory-level papers/texts on multiscale modelling of solids. Please suggest some titles which give introduction alongwith a summary about the latest advances in this field. I will be thankful for your suggestions.

Discontinuities have a fundamental role in the mechanics of solids. The most famous type of discontinuity is a crack, but others are important too, such as dislocations and phase boundaries. Many types of deformation that appear to be continuous at the macroscale, such as plastic flow in metals, really involve the evolution of discontinuities at some smaller scale.

Spatial Control in the Heterogeneous Nucleation of Water

The attache d paper was recently published
in Applied Physics Letters. We show for the first time that Nucleation and
Condensation of Water can be spatially controlled. Such control of nucleation
phenomena and the fundamental findings discussed in the paper have implications
for the Energy and Water industry. The paper can be found at http://link.aip.org/link/?APL/95/094101/1

How to build a contact model involved the plastic defoemation?

Hello, everyone.

Recently, I am trying to build a plastic contact model to describe teh relationship between the plastic deformation and the contact force, which is a crucial point in my work that dealing with the grasp force in robotics. So, anybody has some ideas about this? Actually, I am attempting to find a analytic model.

Stress fields for finite crack in an infinite plate under tension

hi...

 

       I am working on cracks emanating from a hole,  using Complex
stress potential method.  Now i have obtained the Stress Intensity
Factor ( SIF ) and now i want to plot the stress field or stress
contours. please guide me how i can get stress field.

Thanking you.

Yours Sincerely

Crack modeling

 

hi.

 

         I want to model a " Two cracks in infinete plate in ansys" but it is possible to use one quarter point element at a time.

 

    please help me how to model two cracks in ansys or  if it is easily possible in abaqus then also i am interested.

 

thanking you

 

viny
