When we have stress, say in x direction, due to poisson effect, we get strain in y and z directions.
What is the reason that associated stress does not develop due to this strain in y and z directions? Is it due to the fact that there is no restraint to this strain, something similar to when free thermal expansion does not result in stress?
Dear researchers.
I am trying to start studying HIFU (high intensity focused ultrasound) absorption mechanisms and modeling methods, specially for clinical applications(absorption in tissue). But I cant find any straightforward article in this field.Would you please help me on this.
With great Thanks.
Dear all
I need help in executing ANSYS user programmable feature (UPF), specifically subroutine userpr (changing element pressure information) for my 2D model. I have read the manual but don't understand the subroutine program structure (attached below). Can someone kindly explain how can I activate and run the subroutine?
Thanks,
Samuel

For my graduation work (student at the Delft university of Technology, The Netherlands), I am trying to model the aeroelastic behavior of a wind turbine rotor. For this end I use an Abaqus model of a wind turbine blade (which is a composite structure with different fiber layers and corresponding orientation). The aerodynamic force is calculated by a BEM code (Blade Element Momentum theory), which is a simplified engineering aerodynamic code: fast but still quite good. Using CFD to calculate the loads is out of the question since it requires far too much time to calculate.
In joint material interface between elastic and elastic-plastic material, how can we show the continuity of displacement theoretically?It must be continuous and compatible of deformation in practical case.Could anyone help me to understand this answer?
Hi, folks! I'm a new user of Abaqus. Please can you help me with remesh, ALE remesh technique in Abaqus/CAE. May be you have any example in Abaqus/CAE. If you have any, plese me on babichev [at] uiggm.nsc.ru.
Thanks!
HELLO EVERYONE:
FIRST TIME EVER ON THIS SITE, IT IS GREAT!
WELL, IF YOU HAVE QUESTIONS TO ASK JUST SHOOT, I AM BEGGINING AN SPECIALIZATION IN STRENGHT OF MATERIALS AND I MAY KNOW SOME THINGS.
The ability to control the domain patterns in ferroelectric nanostructures holds promise as a method to tailor physical properties for specific applications. We proposed a new way to control the domain patterns in ferroelectric nanostructures. Desirable domain patterns can be obtained through different surface charges. The surface charges can be supplied by the atomic and molecular adsorbates on the surfaces of ferroelectric nanostructures.
The deadline for abstracts for the 21st Annual Melosh Competition has been extended until January 30. All interested graduate students are encouraged to apply.
This competition for the Best Student Paper in Finite Element Analysis will be held at Duke University on Friday, April 24, 2009. The competition has become one of the premier graduate student events in the broad area of computational mechanics.
