NUMERICAL ANALISYS OF DISCONTINUITIES IN BEAM STRUCTURES.

This paper presents specific aspects of the beam structures junctions nonlinear calculus. The substructuring method applied with the help of some high-performance numerical methods is considered the only way to study some high level stress zones. The working methodology has an original character and may be generalized to all structures with geometrical and material discontinuities. The stress state configurations obtained using the finite element method allow a correct evaluation of the safety coefficients and reliability of the analyzed structure. [ABSTRACT FROM AUTHOR]
