Background and Problem statement

Due to increased level of number of test cases, number of strain gages and order of

complexity, which result in huge test and analytical data

Final correlation plots

Testing solution post-process the structural test and analytical data and creates the

correlation plots automatically

1. Automatically extracts Strain gage locations out of CATIA model

2. Automatically extracts the predicted strains from Abaqus/CAE models at strain

gage locations

3. Automatically generate the rapid correlation plots (strain Vs loading, deflection

Vs loading)

Conclusions and Key Learnings from Integrated process

1. The integrated process has been implemented in an integrated CAD and CAE

environment using CATIA V5 and Abaqus/CAE tools. The results of the tool

have been successfully calibrated and validated against test results

2. This integrated process would be applicable across wide range of industrial

applications where extensive structural testing and analytical correlations are

performed

3. Generate quick Test vs analytical correlation reports

Benefits Summary

The integrated tool for strain extraction has helped in reducing the engineering effort by about 90%

The integrated tool can be used for extraction strains of any generic structure with minimum customization, if required
