Factors That Impact Izod Impact Energy

Posted by Claire Smith on December 9th, 2021

The Charpy Izod Pendulum Impact Tester is a high strain-rate test to control the amount of energy captivated by a substance fracture. The Impact tester includes a pendulum of known mass and length released from a known height to strike an Impact Sample. Impact varieties are of standard dimensions in various industry standards, counting ASTM A370, ASTM E23, EN 10045-1, and ISO 148.

It is highly versatile and essential, such as ASTM D256, a standard test technique for strong plastics\' Izod pendulum impact support. This is to measure the dimensions of the plastic substance in terms of solid point and resistance. Here are how it works and some of the things that affect its performance.  

How Is Izod Impact Testing Done?

You place the sample material on the Izod impact tester when you do this testing. The Izod test materials typically have V-notch cuts, and these notches act as a stress absorption region. It also comprises a pivoting arm raised at an altitude equivalent to the continuous potential energy. Then it releases, and the arm hits the substance placed on the impact taster.

So, it absorbs the energy from the arm\'s height and helps evaluate the material\'s relative toughness. These testers are beneficial more as a comparative test and measures in power KJ/m2.

Factors that impact Izod impact energy

The different factors that affect the Izod impact energy are listed below:

•          Notches – some substances are more delicate than others, and the range tip and deepness of the gap are essential.
•          A notching machine is helpful to create this and is used for the cutting, shearing, or punching process on the sheet metal or thin bar stock.
•          In some situations, a broaching machine is beneficial for removing the metal parts. It is ideal to do a keyhole or U-notch on the substance
•          Fracture mechanism- This is the substance\'s capability to handle fracture or harm.
•          Temperature and strain rate – Lower temperatures decrease the elasticity of the materials.
•          Yield strength and flexibility – the impact energy of the substance reduces if the yield strength amplifies.
