What's New in:
The NASGRO® fracture mechanics and
fatigue crack growth analysis software is a suite of computer
programs linked together by a graphical user interface.
NASFLA, the central life
assessment code, contains libraries of stress intensity factor solutions and
material properties and
performs the crack growth analyses.
NASBEM is a two-dimensional (2-D)
boundary element (BEM) code used to calculate stress intensity factors or
stress fields in 2-D geometries.
NASMAT is an extensive database of
material data for fatigue crack growth and fracture analysis.
NASFORM is a fatigue crack formation (initiation)
analysis module containing a stress-life model and four different
NASGRO is operable on
Windows 95/98/2000/XP and Windows 7. NASGRO is compatible with 32-bit and
NASGRO executable programs, DLLs, materials files,
and spectrum files require about 230 megabytes of disk space. In addition,
over 20 megabytes of disk space are required for files that
are generated during the execution of the program.
