[b]ALOAD - a code to determine the concentrated forces equivalent with a distributed pressure field for a FEM analysis[/b]
Journal Title: INCAS BULLETIN - Year 2010, Vol 2, Issue 4
Abstract
The main objective of this paper is to describe a code for calculating an equivalent system of concentrate loads for a FEM analysis. The tables from the Aerodynamic Department contain pressure field for a whole bearing surface, and integrated quantities both for the whole surface and for fixed and mobile part. Usually in a FEM analysis the external loads as concentrated loads equivalent to the distributed pressure field are introduced. These concentrated forces can also be used in static tests. Commercial codes provide solutions for this problem, but what we intend to develop is a code adapted to the user’s specific needs.
