Using this basic formula V= √2*h*g. H represents the height from which the object is dropped to the ground in meters. G represents the pull of gravity.
First check Impact energy from Charpy Imapct testing and cross section of the fractured sample. Calculate Impact strength as per given formula: Impact strength= Impact Energy (In Joules) / Area of cross section (cm2) (J/cm2)
calculation method with example for impact strength?
tensile strength
it is the resistance of material to impact(sudden) loading...or..it is the impact energy absorbed per unit area.
impact strength is sudden load bearing capacity & toughness is steady load bearing capacity.
You measure it. If you want to calculate it, please clarify what information you have available.
no
impact resistance high strength
yield strength = 235 MPa (as implied in the name) tensile strength = 375-460 MPa See the related link for further information. Note that the main difference between different grades of Q235 (e.g. Q235A vs. Q235B) is the impact strength. Q235B has better impact properties than Q235A.

M1 = Fd2 / km2
To calculate the bursting strength of 5 ply corrugated board, the ability to hold weight must be tested first. The bursting strength would be the amount of weight the board can hold before breaking.
