FRANC 3 D Version 5 0 with ANSYS

FRANC 3 D Version 5. 0 with ANSYS

Create an uncracked 3 D model with all boundary conditions, material properties, etc

cut-surface Extract a sub-volume that will contain the crack and define a node component or set of the cut-surface and save this to a. cdb file.

Save the remainder of the model to a different. cdb file.

retained cut-surface mesh facets Import the sub-volume. cdb file into FRANC 3 D and retain the cut-surface mesh facets.

Insert an initial crack into the model. crack front template initial crack

retained cut-surface mesh facets FRANC 3 D inserts the crack into the model and remeshes while retaining the cut-surfacets. initial crack

FRANC 3 D writes a. cdb file containing the cracked mesh information and combines this with the remaining portion of the model.

ANSYS analysis provides displacements, stresses, etc for the full model.

In particular, ANSYS provides the displacements at the crack front, which are used by FRANC 3 D to compute stress intensity factors.

FRANC 3 D computes Modes I, II, and III stress intensity factors along the crack front.

FRANC 3 D uses the computed stress intensity factors to grow the crack.

Crack growth simulations provide stress intensity factor histories for computing fatigue life and indicate crack paths and possible damage scenarios – click slide to play.
