FEACrack--crack propagation analysis software

FEAcrackTM is a 3D crack analysis finite element analysis software produced by QUEST company, which has the function of generating automatic finite element mesh near the crack.It can analyze and solve the stress intensity factor and J integral associated with the crack, The analysis module analyzes the crack propagation. The automatic grid generator can generate the corresponding input grid files for many finite element analysis software ABAQUS, ANSYS, WARP3D and PATRAN and FEMAP.

FEAcrack crack library can be used for different types of cracks automatically generated grid is convenient and convenient, widely used abroad for fracture assessment, crack fatigue analysis and crack geometry study.

Users can use the geometric characteristics of the crack library to define the crack type and geometry, or you can customize the crack: The figure below the hole crack is a custom number of standard library elliptical crack synthesis.

FEAcrack combines the WARP-3D finite element solver to analyze the crack and display and compare the results of the post-processing interface.

Crack edge line J integral

FAD assessment of crack growth and safety

FEAcrack generates a local crack grid, the user can first define the local meshing, and then as a sub-grid to local constraints and the overall contact with the latter through the grid library to find the corresponding model.

FEAcrack supports fatigue analysis of cracks, simulates crack development over time:

FEAcrack easy to understand the interface, 3D grid geometric model library convenient, and a combination of WARP-3D finite element solver, can quickly and easily different models of different types of cracks in the grid and the finite element analysis, FEAcrack also With the post-processing interface, you can import the K, J and other crack analysis of the important parameters and view, you can also import the finite element cloud diagram, see stress and strain.
