Our Mission

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

The technological basis for this mission is a suite of analysis and simulation programs which integrate linear and non-linear fracture mechanics with finite and boundary element methods, advanced geometry and mesh  models representations and database design, automatic mesh generation and modification, and effective computer visualization.

FAC recognizes the need for agility in responding to today’s rapidly changing corporate engineering environments.  We provide client-specific component analysis, failure analysis, structural health prognosis, collaborative analysis, software installation and support, customized software, and training workshops.

Our Software

Our unique software has been developed specifically for analysis and simulation of arbitrary crack growth, in arbitrary structures, under arbitrary boundary and initial conditions. We rigorously separate the tasks of meshing from those of geometry representation so that cracks can take any shape predicted by the physics and mechanics of the problem at hand, without any crack shape restrictions or other simplifying assumptions.  Our software is highly interactive and graphical, and all remeshing associated with non-planar, arbitrary crack propagation is performed automatically.

bullet FRANC2D: Constructed on a winged-edge database, FRANC2D performs FEM-based simulations of curvilinear crack growth for 2D/axisymmetric structures.  FRANC2D can compute mixed-mode stress intensity factors very accurately, and can also perform elasto-plastic and cohesive non-linear crack growth analyses.   Increasingly capable versions of FRANC2D have been in worldwide use for over 15 years.  FRANC2D is available for UNIX, LINUX, and WINDOWS platforms.
 
bullet FRANC2D/L:  This adaptation of FRANC2D has special capabilities for simulating crack growth in any layer of a multiply-layered structure, such as a lap joint or composite repair patch, where the layers are either connected through adhesive or mechanical connectors.  FRANC2D/L is also available for UNIX, LINUX, and WINDOWS platforms.
 
bullet FRANC3D: Constructed on a radial-edged database, FRANC3D is designed to work in consort with general-purpose, commercial 3D finite element and boundary element programs that do not have crack growth simulation capabilities.  FRANC3D provides solid modeling and necessary preprocessing, meshing, and result visualization capabilities.  It performs fracture mechanics calculations, results mapping, and automatic remeshing reuired to simulate non-planar 3D crack growth.  FRANC3D is also available for UNIX, LINUX, and WINDOWS platforms.

Our Clients

Using our FRANC family of codes as the basis for analysis and simulation, FAC provides engineering consulting, education, and training services to a broad spectrum of industrial and government clients in:

bullet Turbo-machinery: failure analysis and prognosis in steam and gas turbine components.
 
bullet Manufacturing: process simulation and failure analysis in metallic, ceramic, polymer, and composite components.
 
bullet Aerospace: failure analysis, structural health prognosis, and life and residual strength analyses in solid, pressure vessel, and stiffened shell components.
 
bullet Geomechanics/Civil Structures: rock fracture, cracking in concrete and steel structures.

Principals

Dr. Anthony “Tony” Ingraffea, Ph.D. (Colorado, 1977), P.E. (Colorado and New York) has 30 years of experience in structural mechanics.  He is President of FAC, and the Dwight C. Baum Professor of Engineering at Cornell University where he has co-authored with his students and research associates over 200 papers in computational and experimental fracture mechanics, and directed over $27M in externally-funded R&D.

Dr. Paul “Wash” Wawrzynek, Ph.D. (Cornell, 1991) has over 20 years of experience in computational fracture mechanics.  He is Chief Technology Officer of FAC, is the principal author of the FRANC suite of codes, and specializes in turbo-machinery and aerospace structures. Wash is also a Senior Research Associate at Cornell University as a member of the Cornell Fracture Group.

Dr. Bruce Carter, Ph. D. (Manitoba, 1992), has over 20 years of experience in geomechanics and computational fracture mechanics.  He is FAC’s Principal Engineer, and specializes in simulation of crack growth in complex turbo-machinery components and in coupled fluid-fracture processes. Bruce is a member of the Cornell Fracture Group also.
