NONLINEAR ANALYSIS OF INTERSECTING CYCLINDERS BY THE FINITE ELEMENT METHOD

A finite element procedure is presented for the analysis of intersecting cylinders with elastic-plastic bahavior. A special layered system is utilized in the region of the intersection where the high stress gradient exists while two-dimensional curved shell elements are used throughout the remainder of the structure, this to minimize computational efforts. A problem of two normally intersecting cylinders under internal pressure is solved. The stresses as the outer and inner fibers of the shells are evaluated and compared with available experimental data. It is found that yielding starts from the region where the two cylindrical walls intersect perpendicularly, then spreads out along the intersection line with increased load.
