Izod Impact Testing Instructional Video

[@knvcsg1839]

The ending got me! 😂😂 'Be careful while performing this test and have fun! '

[@impactodelsurenterprise2440]

A moment of silence for the decapitated little guy.

[@ssd7385]

Thanks a lot. U saved my day and my specimen

[@Tadaisme101]

thanks very clear explanantion on the steps!!

[@kshithijrai6116]

Nice video.Thanks!!

[@mohamedarthil6249]

clear explanation !! could have shown the specimen

[@AsifKattakath]

super...

Iam 300 th subscriber☺😊

[@sajeenaanwar7786]

thankuuu very much

[@choirthejourney]

thanks a lot teacher 👍👍

This is a prehistoric machine, you need a modern machine

[@philhealey4443]

What new features would you want, although the clamping arrangement looks fairly tired.

[@shreenivasap.h3073]

very good video

[@saqibabbasi116]

nice explanation but there is too much movement of camera

[@arifernanda5982]

thanks

[@affanahmedkhan7362]

shukria ❤️

[@jackmccowan2246]

what is the difference between this and charpy test?

[@JB-yl4re]

Hello. The Charpy test typically holds the specimen horizontally and the Izod test holds the specimen vertically. Thanks!

[@danetogibbons]

What's the purpose of the V notch?

[@jeremybraithwaite1232]

The V-Notch allows stresses to build and failure in a predefined area that has been machined to a standard and controlled size. This will also give us more accurate comparative statistics when testing different materials or material conditions. Thanks for the question!

[@danetogibbons]

Thanks much, I get it now.@@jeremybraithwaite1232

[@mambajorgeiiic.462]

What is the acceptable result in izod test? How can we say for example a composite material is safe to use?

[@JB-yl4re]

Hello, good question! This testing method is used to determine the amount of impact energy (ft/lb) required to break a specimen of a specific material at a specific temperature. We use this data to help inform the material selection process when designing parts for various scenarios. Acceptability would be a material that fails above the forces you expect your part to experience. I will also say that this provides us with data to help us make informed decisions about choosing materials and coupled with virtual simulation these types of tests are very valuable; however, they do not take the place of real-world prototype testing. I hope this was helpful. Happy making!

[@mambajorgeiiic.462]

@@JB-yl4re What usually is the force we are targetting for us to say the material is acceptable?

[@JB-yl4re]

@mambajorgeiiic.462 It changes based on the material and the application.

[@skitidet4302]

Isn't he exaggerating the danger quite a bit? I know he's talking to engineers, but even they should be able to handle such a simple practical task without injuring themselves.

[@adventuresinphysics5069]

0:29-0:31 should read "there's a lot of potential energy stored in there" not "kinetic energy". The potential energy is converted to kinetic just when it begins to fall. I stand to be corrected. Thank you

[@JB-yl4re]

Thank you - you are correct.

[@MuadDib___]

Was about to type this. All the Ghana boys are smart.. 😁

[@vivekpapola9382]

sir please reply hoe you use brake

[@JB-yl4re]

The brake is applied by pushing in the center knob.
