Checking Plastic Flexural Strength

This video focuses on checking and testing plastic flexural strength.
We need to understand how plastics can resist deformation under load in order to know their suitability for our products.
You'll see a flexural test setup, how a test is performed, and the parameters we test to.
We also include some common plastic materials and their respective flexural properties so that you can select the best type for your job.

the simplest yet clearest explanation I found on youtube for this specific subject (thank you)

Happy to help! 😊

Your explanation of flexural strenght is incorrect per the technical definitions I read; in a material that returns to its original shape after bending, when it deforms by 5% that is considered its flexural strength, in material that does not return to its original shape after distortion; as soon as its distorts that is considered the material's flexural strength.

The linear stress\strain graph says that it only continues to 2% then most of the ductile materials reach the yielding point
