Code Overview

   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 strain-life models.
     

  • NASGRO is operable on Windows 7, Windows XP, and earlier versions of Windows. NASGRO is compatible with 32-bit and 64-bit machines.
     

  • 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.
