About UFLEX
UFLEX can be used both for the purpose of producing capacity curves and for performing fatigue analyses of umbilical cables. For fatigue analyses, a global analysis is performed for obtaining the correct cyclic variations of bending and tension. These loads are applied as input to local analysis performed using UFLEX2D; subjecting the umbilical cable to temperature, internal and external pressure loads in addition to the axial tension and bending cycles.
