Ansys- Composite materials

Submitted by Manohar Reddy Y P on

Hi all,

Iam presently using Ansys Composite Prepost (ACP) for composite material modelling. I looked at some tutorials and understood the procedure, but when I applied it to simple case of simply supported rectangular plate with uniform load, the results donot match the theoritical textbook results. I tried it in ANSYS Mechanical APDL, the results were exactly same with  theoritical value. Iam unable to find the mistake. Is it possible to get the validation results for ACP similar to the validation results which are available for ANSYS APDL(provided by ANSYS ).

Flow Induced Vibration in pipe flow

Submitted by kdevarajanmts on

Hi all

 

I am doing flow induced vibration analysis in pipe using ansys workbench. First i created fluent model and this output(solution) is couple with tranient structural  setup. FInally the pipe gets displaced becuase of fluid pressure. After that i want to calculate the modes. So it is possible to couple transient structural solution to modal setup? I have tried but i didnt know how to couple modal analysis and transiest structural analysis. Please help me regarding in this.

Plasticity and non-Schmid effects

Submitted by Stefan C. Soare on

If slip is the only mechanism of
plastic deformation of a crystal and Schmid law governs the slip
activity, the overall response of an aggregate of such crystals
features the normality rule of classical plasticity, see
node/15347
for a rigorous recent proof. Any deviation from Schmid law is
referred to as a non-Schmid effect. In general, these effects may be
of two kinds: in addition to the resolved shear stress (on a slip
system), other stress components may influence slip activity or/and
the hardening of a slip system (representative examples for each kind
are described, for example, in Qin and Bassani(1992) and Spitzig

Plastic Spin

Submitted by Stefan C. Soare on

In the classical (rate-independent)
theory of metal plasticity, the plastic spin has been an issue of
research and debate for about thirty years. Judging by the content
of current publications on the topic (regarding modeling
possibilities, consequences and applications), it seems that the
concept has acquired a certain degree of acceptance, although no
rigorous justification, at theoretical level, has ever been provided.
In the attached preprint this matter is investigated starting from
