Value PropositionStress Analysis

“Virtual.Lab Structures decreases the time for iterative stress analysis more than 70%”

“Virtual.Lab Structures decreases the time for initial stress analysis by 30%”

1. Integrated Environment1. Integrated Environment 2. Fast Iterative Analysis2. Fast Iterative Analysis

Over 60%Over 60% Average Time Saving Per Component AnalysisAverage Time Saving Per Component Analysis


Economic Impact Analysis Assumptions

Average fully costed cost of an engineer ~ $220K

The company has an internal rate of return ~ 5%

To complete an analysis it takes ~ 10 reruns

There is no break in the associativity of the stress analysis process

There are 200 stress engineers at the company

Note Note -- Although the cost advantage could be used to reduce workforce, Although the cost advantage could be used to reduce workforce, the real the real competitive advantage is the agility the manufacturer gets like competitive advantage is the agility the manufacturer gets like for example being able for example being able to producing more designs for the same cost or develop better opto producing more designs for the same cost or develop better optimized designstimized designs
