CAI Compression Test

The pre-damaged specimens are tested in a special compression tool to establish the residual compression strength. 

The resulting compression forces are usually very large. 

To load the test plates without buckling, special compression tools are used that are distinct within the standardization: 

ASTM, Boeing, SACMA and DIN: All four sides are guided, but not clamped. 

ISO, EN and Airbus standards: The upper and lower ends of the specimen are clamped. The sides are guided with line contact
