Overview
FatigueWizard is an innovative software product which will enable any CAE
engineer to utilise results of a finite element analysis to carry out
sophisticated and accurate fatigue life calculation
It has been developed by CAE engineers with over 30 years combined
experience/knowledge of finite element analysis and durability assessment.
As such it is a tool designed by engineers for engineers. Fully functional yet
easy to use.
FatigueWizard has been developed to enable even inexperienced CAE analysts to
complete effective durability assessment. It utilises an innovative 'wizard'
interface designed to lead the user through the steps necessary to perform
complex fatigue life calculation. Results can be viewed as life or safety factor
using the FatigueWizard post processor or exported and viewed in the native FE
software. The FatigueWizard can then be used to generate customisable reports
with minimum effort or time.
FatigueWizard makes complex fatigue life assessment both achievable and affordable.
The benefits of performing durability assesment as part of the design
process are well known. FatigueWizard will realise these benefits for those who
previously may not have had the skills or budgets.

Fully Functioning (SN and EN)
FatigueWizard is fully capable of performing sophisticated fatigue life
analyses; from conventional stress based analyses to 'low cycle' strain based
analyses with plasticity correction. Mean stress corrections can be accounted
for using standard methods and endurance modifiers such as surface finish,
temperature etc are all available to the user. For a complete list of the
capabilities within the FatigueWizard follow the features link.

Multiple Loadcases (Non-Proportional)
FatigueWizard is fully capable of performing fatigue calculations using stress
results from multiple loadcases. Results from
multiple loadcases can be scaled individually using separate load histories of
up to 30000 points and analysed as a combined loadcase. Alternatively, stress
states from individual loadcases can be used in sequence to produce the cyclic
stress history.
Each loadcase and load history can be individually scaled to
determine the sensitivity of fatigue life to loadcase.

Material Database
Any successful fatigue analysis is dependant entirely on accurate material
data. FatigueWizard is shipped with an extensive material database. The database
contains material data for stress life curves (SN) and strain life curves (EN)
together with component data for welded joints to BS7608. The databse is fully
editable allowing users to add data as it is made available.
FatigueWizard also includes the capability to 'estimate' strain life material
data, from readily available mechanical properties, using standard empirical
relationships.

Post Processing
FatigueWizard includes post processing tools to complete a fully functioning
easy to use tool. An OpenGL results post processor is included within the wizard
interface to enable the user to view life contours or safety factor contours
before stepping back to perform 'what-if' analyses. If the user wishes there is
also the facility to export FatigueWizard results to formats which may be
read back into the native FE software/postprocessor.
FatigueWizard also includes an automated report writer which enables the user to
quickly create and export summary reports of the analyses just performed. This
can be used to save considerable time and effort compiling written reports and
maximising the time available for analysis.

Analysis Options
FatigueWizard gives the more experienced user a greater choice through
additional 'advanced' forms. Analysis options can be selected to control which
mean stress corrections are to be used, which FEA stresses are to be used and
what portion of the FE model is to be analysed based on a ranked maximum stress
range.
Fatigue calculations may be peformed using equivalent stresses such as signed
von mises, tresca and maximum absolute principal stress. Alternatively, a
critical plane approach is implemented using resolved surface normal or shear
stress.

Analysis Speed
FatigueWizard offers the user several choices to aid speed of calculation. Each
of these may be selected individually depending upon the required speed,
reliability and desired output.
The user may choose to analyse all of the model or parts of the model. The
model may be selectively analysed based on user defined 'groups' or by a given
percentage of nodes based on a ranked nodal maximum stress range.
