field data transfer

Submitted by EL HRAIECH Amine on

Hi,

I am actually working of field data transfer techniques when remeshing is needed during analysis of metal forming process.

some
researchers use a so called Linear interpolation technique using the
volume coordinates as shape functions to transfer a field from a mesh
to an other.

 Is there any one who used this technique in such a problem? 

If there is any, could he tell me which are the advantages of the technique and its disadvantage?

Is there any tests to validate the method?

Multiple interacting three-dimensional flaws in electromagnetothermoelastic coupled multiphase composites by extended hypersing

Submitted by BoJing Zhu on
research

This work presents extended hypersingular integral equation (E-HIE) method to analyze the multiple interacting three-dimensional mixed-mode flaws problem in electromagnetothermoelastic coupled multiphase composites (EMTE-CMCs) under extended electro-magneto-thermo-elastic coupled loads through intricate theoretical analysis and numerical simulations.

Does anybody can recommend me a book on interface fracture of bi-materials?

Does anybody can recommend me a book on interface fracture of bi-materials? I am a layman on this and need your help. Thank you!

Best wishes

Strain Gradient Plasticity

gradient

Recently, there have been many strain gradient theories that are used for the interpretation of size effect at the micron and submicron length scales. The basic idea of these theories is the introduction of a first, or second (or both) gradients of strain or any internal state variable in the governing equations of classical theories.

The development of Crystal plasticity?

Recent experiment have shown the size effect of the materials, when the characteristic length associated with non-uiform plastic deformation is on the scale of micros.The classic plasticity theories can't explain such phenomenon as their constitutive models posses no intrinsic length scale. The new models which contain strain gradient plasticity now are used to explain the experiment.
