• 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.

• 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

• 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

Fatigue Analysis why do it? Widely estimated
that 90 of structural engineering failure occurs
as a result of fatigue

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!

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

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.
