What is Impact Strength? Matmatch

Impact strength also called impact toughness is the amount of energy that a material can withstand when the said load is suddenly applied to it. It may also be defined as the threshold of force per unit area before the material undergoes fracture.

Dynamic crushing strength of hexagonal honeycombs

2010-5-1  In the present paper, we deduce an analytical formula for the dynamic crushing strength in terms of the impact velocity and the thickness ratio for hexagonal honeycombs based on the collapse mechanism of cell structures under impact conditions. As a result, the locking strain of the honeycomb will be related to the honeycomb's relative density.
