Compression Testing - an overview | ScienceDirect Topics

Compression testing is essential, insofar as the compressive strength of an FRP may be very different from its tensile strength. A major difficulty is that the use of flat, straight-sided coupons, while convenient from a practical point of view, may require a reduced gage length if buckling is to be avoided in uniaxial compression, depending on the nature of the specimen.
