Course on 3D Fracture Mechanics Simulation using FRANC3D

About Course

This training course aims to cover the theoretical and practical aspects of Fracture Mechanics with 3D crack growth simulation to estimate the life. We will be using FRANC3D along with general purpose FEM Simulation Software's.


This course mainly deals with the 3D Crack growth Simulation using FRANC3D.

The FRacture ANalysis Code 3D (FRANC3D) program is designed to simulate 3D crack growth in engineering structures where the component geometry, local loading conditions, and the evolutionary crack geometry can be arbitrarily complex. It is designed to be used as a companion to general purpose Finite Element (FE) solvers.

FRANC3D is developed and Fracture Analysis Consultants, Inc. (FAC) was founded in 1988 as a spin-off from high-technology R&D at Cornell University. With an mission to provide state-of-the-art services in computational fracture mechanics to industry.

Understanding the FRANC3D process:
  • an analyst creates an uncracked FE mesh using the standard tools available in the commercial FE package.
  • The analyst then defines a sub-model of the crack growth region.
  • FRANC3D reads the sub-model mesh file and remeshes the sub-model to incorporate the geometry of a crack. The crack geometry and location can be prescribed interactively using the Graphical User Interface (GUI).
  • The “cracked” sub-model is reintegrated into the remainder of the model and an analysis is performed.
  • The resulting displacements are read back into FRANC3D, which computes Stress Intensity Factors (SIF’s) for all node points along the crack front.
  • The SIF’s are used to predict the direction and relative amount of growth of the crack front points.
    The crack is extended, the sub-model remeshed, and another stress analysis is performed. This process is repeated for the number of crack steps specified by the analyst

This course will cover theory and hands on aspects of 3D Crack Growth Simulation.
