title = "FEM and fatigue life calculation using the PC-based NISA II/ENDURE -software package",
abstract = "The fatigue life prediction capability of the NISA II / ENDURE -software package is studied. The software is used to calculate the fatigue life of three types of specimens, which were all previously fatigue-tested in the laboratory. The overall properties of the NISA II finite element program are introduced. The fatigue analysis program ENDURE is introduced more comprehensively. ENDURE can be used for fatigue calculation with the FEM stress results or as a stand-alone program. The crack initiation calculation is based on the local strain approach, and crack propagation is predicted using fracture mechanics. The crack initiation calculation was tested in this context. The main reason for choosing the NISA II / ENDURE -program was that at the time of writing it was, as far as the author could tell, the only FEM-integrated fatigue life calculation program on the market. This is a very interesting feature and some other vendors have launched their own FEM-integrated fatigue programs during 1990. The other reason for choosing the program was the load description capabilities of ENDURE. Loads can be applied to a structure in various ways. Two main categories of loads are used: deterministic and stochastic loading. These are briefly dealt with in the report.",
