compressive rate in cube crushing test for women

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 straightsided 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
