Abstract : The primary technical objective was to assure that the criteria for evaluation of the engineering software packages NASTRAN, ADINA, and STAGS were implemented by the individual evaluation contractors, and to review and monitor the evaluation activities. Several secondary objectives were also defined. These included a review and assessment of the use of large deformation, inelastic finite element programs--such as HONDO and DYNA3D--for design calculations; recommendations on flaw acceptance criteria for weldments in structures operating at elevated temperature; a description of the methods and procedures available to analyze low-velocity puncture of protective structures; and a fatigue assessment for offshore structures.
