I input into MAPLE the following differential eq & it returned that it is classified as an Emden-Fowler Differential Equation:
r^2*F"+1/r*F'-k^2*F=0 where F is a function of r
MAPLE was able to generate a solution. I am attempting to figure out how this eq is actually solved & I typed in Emden-Fowler into the SEARCH window on this website & got ZERO results.
Hello all,
I want to model hydroplaning problem in abaqus. how to simulate water component in between tire and a pavement in abaqus.
I want to use either Coupled-Eulerian-Lagrangian algorithm or Aribitrary-Lagrangian-Eulerian algorithm at the contact patch but i could find any one of these features in abaqus.
Please tell me in detail, if any one has done this problem in abaqus.
Thanks a lot

Hi all,
I am a PhD student at the first months. I have to choose a finite element software to study impact effect on biological soft tissues. After some web researches the softwares which seem to be more suitable are ABAQUS, Comsol Multiphisics and Ansys.
My intention is to develop an user defined material model considering the material as anisotropic porous-visco-elastic.
I would appreciate some suggestions/opinion. I am specially interested in dynamical simulations.

Hi all,
I have some
problems with understanding correctly the stress (e.g. Cauchy stress)
calculated by Abaqus. The boundary value problem consists of a square
where the top side is displaced up by 20% of its original height while
the bottom side is fixed. Now when I use a quadrilateral mesh the
result is clear. But what happens when a triangular mesh is used? Why
some triangles have a negative stress? In the figures the S11
component of the Cauchy stress tensor is plotted.
Best regards,
Barbara
Hi,
I have encountered fourth order space derivative in the PDE derived for
smart material.I am looking for the physical significance of higher
order spatial derivative of displacment in longitudnal loading. In the
Euler-Bernoulli beam theory (lateral loading), the fourth order space
derivative referes to the load.
In longitudinal loading, the first order space derivative is strain i.e
du/dx .What are the significane of higher order space derivatives d^2
u/dx^2 , d^3 u/dx^3 , d^4 u/dx^4?
Please share your expertise.
A Summer School on Fracture will be held at the Institue d’Etudes Scientifiques de Cargèse, during June 7 – 19, 2010. You can find detailed information about the school, the topics covered, lecturers, accommodation, travel, etc at the following websites: http://www.ae.utexas.edu/SummerSchoolFracture/, http://www.iesc.univ-corse.fr/spip.php?rubrique143/
hi all,
Why the stress values are on Y-axis and strain values on X-axis?
If we interchange the stress on X axis and strain on Y axis , will there be any change or is it possible to change?

Hi, I am looking for an opensource FEM tool to solve thermoelectric problems which involve seebeck and peltier effect. Any suggestion?
Hi!
I have written the program in C++ which is based on one of BEM (Method
of fictitious loadings) . I know there are a lot of open libraries of
functions for programming for example openCV or OpenFEM. I could not
find Open Source library for BEM. Please if you know them, give links.
Thanks and Regards,
Marat
A postdoctoral fellow is sought to study the mechanics of magnesium alloys at the University of Waterloo, Canada, under the guidance of Dr. Worswick and Dr. Gracie. The qualified applicant will have a proven background in computational mechanics, substantiated by publications in international journals. Preference will be given to candidates with experience coding large deformation plasticity models, coding the finite element method and with using fracture mechanics. In addition, experience with high strain rate testing of materials is desirable.
