About Intergration Points in Eulerian Element (pls help)

Submitted by sujan on

Hi!

Good Day.

Please note that I am doing Coupled Eulerian lagrangian(CEL) Analysis using ABAQUS. In this technique, mesh is fixed and material will flow through fixed mesh.

 My question is:

1.Are integration points for Eulerian elements are fixed with mesh?

2.If it is fixed, how integration point captured the material behavior (as material is moving through fixed mesh)?

Thanks in advance.

Look forward for your kind reply.

Sincerely-

Sujan.

crack-tip stress field

Submitted by s.r.ranganatha on

I am a post graduate student in mechanical engineering,
as  a part of curriculum  I am doing my thesis  work on fracture mechanics. My thesis title
is “ STUDIES ON CRACK-TIP STRESS FIELDS IN HOMOGENEOUS SOLIDS”.I  have modeled crack-tip using modified
boundary  layer. I have analysed  S22 (tangential stress) for T/σ=0, T/σ=0.34
&  T/σ=+1.my values are matching with
N.P.O’DOWD and C.F.SHIH for T/σ=0 and T/σ=0.34. But for T/σ=+1 the values of
S22 are coming for less than HRR
values.

Dear Experts,

I have a bit of confusion regarding jacobian interpretation in finite element analysis.What does Jacobian signifies here? Is this just a transformation matrix between two sets of co-ordinate systems or is it a measure of the deforamtion (streching/shearing) of a mesh element?

Any particlar citation for reference?

Theoretical investigation on polar dielectric with large electrocaloric effect as cooling devices

Submitted by Bo Li on

Polar dielectric based cooling devices are
modeled as a system with two degrees of freedom and represented by either an
entropy-temperature or electric displacement-electric field plane. A typical
thermodynamic energy cyclic path is proposed for polar dielectric as cooling
devices to experience. With the influence of temperature taken into
consideration, the free energy of a thermal electrical coupling system of polar
dielectrics is formulated, and the variation of temperature and entropy, the
absorption of heat, and the work under different electric fields are calculated
for BaTiO3, Pb(ZrxTi1-x)O3, P(VDF-TrFE), and water. And the simulation results
obtained agree well with the recently published experimental data [B. Neese, et
