Crush testing approach for flat-plate fibrous

A coupon-level test-method was developed by Jackson et al. [17,20] for characterizing the energy absorption of flat-plate specimens.The main problem with testing flat-plate specimens is global buckling, which needs to be prevented in order to ensure sustained crushing under compressive loading [17,20].Therefore, buckling analysis was needed to determine the appropriate plate dimensions.
