1. 1
Metal fatigue causes a wide majority of structural failures and accidents
in ALL industries. In aerospace for instance, the number is said to be a
whopping 90%. Fracture Mechanics is an indispensable tool we have, to
minimize the occurrence of failures in components that can result in great
loss of life or at the very least will necessitate often expensive repairs. Loss
of profits or erosion of national defense postures will also be the result of
inadequate attention to metal fatigue dangers.
Fracture Mechanics pervades all aspects of material procurement,
product design, development, manufacture, assembly, usage, quality
assurance and maintenance.
The use of Fracture Mechanics and Failure Assessment techniques to
assess performance, reliability and to prevent or minimize potential
failureshasbeenontheriseinvariousindustries.Incorrectmanufacturing
processes and inadequate attention to prevent corrosion and fatigue can
affect the reliability and performance of materials and structures. Early
understanding and detection of flaws or cracks and the understanding of
the tolerance of components and materials enables early understanding
and assessment of reliability and overall integrity of materials that
ultimately reduce crucial failures.
WHY YOU CANNOT MISS THIS EVENT
This Training Program will cover fatigue and fracture principles and provide
an understanding of failure assessments. Delegates will be exposed to
methodologies, techniques and tools in the study and prediction process.
Quality training programs on Fracture Mechanics and Fatigue concepts are
rare, especially in Asia.An added bonus is the hands-on tutorials aided by the
instructor.Product failures can kill people and cause huge expensive losses. You
should be armed with the latest concepts in Fracture Mechanics and Damage
Tolerance to be able to better protect your structures and equipment from
the unrelenting attack by metal fatigue. You will learn these concepts from an
experienced and dynamic leader in the field of Fatigue and Damage Tolerance.
This course is for Engineers involved in materials, design, mechanics, structures,
reliability, pipeline well as those involved in the testing and fabrication side
covering various industries like aviation, oil & gas, utilities, etc.

Sam Kantimathi is based in California. His speciality is
in metal fatigue, fracture mechanics, damage tolerance
analysis. Prior to founding his company, Sam held senior
engineering positions at AeroStructures, Inc and Beech
Aircraft Corporation, where he completed fatigue and
fracture mechanics substantiation of Beechject400,
Commuter Model 1900 and the King Air.
At AeroStructures his responsibilities included fatigue
and fracture mechanic evaluations of helicopter and
fixed wing aircraft structures. He developed and installed
a fatigue crack initiation tracking program for the F-4S
fleet in the US Navy. It was the first sequence-accountable
scheme employed by the Naval Air Development Center
for its quarterly “Structural Appraisal of Fatigue Effects”
(SAFE) reports.
RecentlyhehasconductedcoursesforPrincetonUniversity
and numerous organizations including Boeing Company,
Northwest Airlines, FAA, Singapore Airlines and US Navy,
and dozens of companies in five continents. For 4 recent
years, he was the sole instructor in his workshop at George
Washington University entitled “Minimizing the Danger
of Fatigue in Metals and Composites.” He also prepares
and executes a phenomenally successful course for the
American Institute of Aeronautics and Astronautics (AIAA)
called “Fracture Mechanics - Aerospace Applications” and
also one on Advanced Fracture Mechanics.
AIAA added his course entitled “Aerospace Structural
Accidents” to its course offerings in 1995. He has
taught graduate and undergraduate courses in design
methods, fatigue, wear, fracture and materials. He is an
Associate Fellow of AIAA and serves on committee E08
on fatigue and fracture of American Society for Testing
and Materials, (ASTM). He belongs to ASM International.
He is also affiliated with American Society for Training
and Development, American Defense Preparedness
Association, and American Helicopter Society. Sam
Kantimathi earned a BS Degree in Mechanical Engineering
from the Indian Institute of Technology and a MS Degree
in Mechanical Engineering from Wichita State University.
Lockheed Martin, MOOG and LORD Corporation are
among the companies that have utilized Sam’s consulting.
