The only way to prevent this problem is to know the dynamic behaviour of the machine in design phase, by finite element method calculations. We made such a study on an our pump. Many approximations were made and the model is somehow poor, nevertheless the results were encouraging....
A numerical method for calculating linear acoustic fields in axisymmetric regions containing a subsonic irrotational gas flow is developed. The boundaries of the regions under consideration can contain portions corresponding to open space. The calculation scheme is based on the finite-element method, ...
the designer rests on empirical experience and constructs for example chairs with dimensions of structural members based on tradition and aesthetic reasons. By the much more common use of computers it is nowadays possible to use modern finite element programs in various stages...
The SAFEM outperforms the AFEM in modelling traction-free cracks. Keywords: augmented finite element method; finite element analysis; drilling degrees of freedom; cohesive zone modelling; crack modelling; strong discontinuities; embedded finite element method...

It is worth giving a bit of historical context. The mathematics behind thefinite element methodwas developed well before the first electronic computers. Thefirst computers to run finite element programswere full of vacuum tubes and hand-wired circuitry, and although the invention of transistors led ...

The element free Galerkin method is a global method while finite elements method is a local one. This technique employs a background mesh for integration which makes it different from the truly mesh procedures. The coefficient matrix of the element free Galerkin is symmetric. Also, using ...
