摘要: This paper discusses the energy-absorbing effectiveness factor which provides a ratio between energy absorbed in structural system with total potentially available elastic and plastic strain energies all materials used construction. Experimental numerical predictions for are expressed terms of solidity ratio, or relative density, various tubes multicellular sections subjected to static impact axial loadings. The illustrates systems when compared simple regular geometries. effect infilling is discussed along several other factors. useful dimensionless quantity assist choice efficient designs require an capability.
