New Findings from G. Guguin and Co-Authors Describe Advances in Computational Engineering

May 7, 2014



By a News Reporter-Staff News Editor at Journal of Engineering -- Researchers detail new data in Computational Engineering. According to news reporting from Toulouse, France, by VerticalNews journalists, research stated, "In order to simulate the mechanical behavior of large structures assembled from thin composite panels, we propose a coupling technique, which substitutes local 3D models for the global plate model in the critical zones where plate modeling is inadequate. The transition from 3D to 2D is based on stress and displacement distributions associated with Saint-Venant problems, which are precalculated automatically for a simple 3D cell."

The news correspondents obtained a quote from the research, "The hybrid plate/3D model is obtained after convergence of a series of iterations between a global plate model of the structure and localized 3D models of the critical zones. This technique is nonintrusive because the global calculations can be carried out using commercial software."

According to the news reporters, the research concluded: "Evaluation tests show that convergence is fast and that the resulting hybrid model is very close to a full 3D model."
