  • Fatigue what is it?
  • Fatigue is a process by which a component is
    weakened by repeated bending or other cyclic
    stress, often to the point of fracture.
  • The stress can be small enough to be below the
    ultimate tensile stress, or even the yield stress
    of the material.
  • Over a large number of cycles the effect can be
    catastrophic.

3
  • Fatigue Analysis what is it?
  • Calculation of number of repetitions of load
    before failure
  • Expressed as component life cycles, hours,
    flights etc
  • May be calculated from measured strain history
    or predicted static stresses

4
  • Fatigue Analysis why do it?
  • Improved product quality
  • Optimized design weight/function
  • Greatly reduced warranty costs
  • Reduced costs/time to market
  • Saves both money lives

5
Fatigue Analysis why do it? Widely estimated
that 90 of structural engineering failure occurs
as a result of fatigue
6
Fatigue Analysis why do it?
De Haviland Comet
3 Crash between 1953 and 1954 Fleet
grounded Fatigue of fuselage around windows due
to cyclic pressure loading
7
Fatigue Analysis why do it?
Alexander Kielland Oil Drilling Platform
1980 Catastrophic collapse 123 killed Fatigue of
a main support brace due to repeated wave
loading
8
Fatigue Analysis How should you do it?
  • Physical test -- Expensive and slow
  • requires physical
    prototypes
  • Hand calculation -- Limited application,
  • requires
    expertise
  • Fatigue Wizard -- EASY COST EFFECTIVE!

9
Our Mission
  • To make fatigue analysis both achievable and
    affordable for a wider user base.
  • Achievable through well designed EASY to use
    software requiring minimum training and prior
    knowledge of fatigue theory
  • Affordable through targeted functionality

10
Our Software

FatigueWizard is an innovative software product
designed to enable any engineer to carry out
sophisticated fatigue life analysis using FE
stress results. A Windows style wizard takes the
user through fatigue analysis which will guide
even the novice CAE engineer through the steps
necessary to perform complex analysis.
