| Abstract: | Experimental studies are carried outon 24 specimens of mild steel, stainless steel and copper metalliccylindrical tubes of six specifications under axialcompress of rigidcone-shaped plate with cone semi-angles 21.8 and 45 and on 20 specimens of mild steel, stainlesssteel of four specifications ofrigid cone-shaped plate with a cone semi-angle 45.The distortionmodes of all samples are obtained. The process of energy absorption is analyzed by load-displacement relation curves. |
