Fatigue analysis software gains Nastran interface

Safe Technology has added a further FEA interface to fe-safe, further increasing the neutrality of its suite of durability analysis software for finite element models.

Safe Technology has added a further FEA interface to fe-safe, further increasing the neutrality of its suite of durability analysis software for finite element models.

fe-safe v5.00-11, is now available with a direct interface to the Nastran Output2 file format.

This is a major subrelease of fe-safev5, released by Safe Technology in January.

The new interface can be downloaded by Nastran users direct from the Safe Technology website.

Other new developments also now incorporated in fe-safev5.00-11 include: influence coefficients - evaluation of the individual contribution of a unit load on the strains or stresses in a particular direction; and gauge outputs - which enables the strains or stresses in a particular direction to be exported.

This is in addition to the extended capabilities and substantial increases in speed of analysis and ease of use already incorporated in fe-safev5.

These include: complex loading conditions and advanced multiaxial fatigue capabilities; fatigue analysis of cast iron; fatigue analysis of welded structures; high temperature and creep fatigue analysis; fe-rotate (quick analysis of axi-symmetric components); thermomechanical fatigue analysis; comprehensive signal processing capabilities (safe4fatigue); and default algorithms (automatic selection of the most appropriate method of fatigue analysis based on the selected material, ensuring ease of use for even the nonspecialist engineer).
