Three Point Bend Test

This video is a demonstration of a three-point bending test to help illustrate to the viewer a standard force-displacement curve that is characteristic of this type of test.

I am your number 1 fan! Your videos make a lot of sense!

Great work
I know a lot of people who use an Instron machine for testing rat and mouse bones.

Got to be careful with cross contamination. You touched your mouse with, and without the glove. Not sure if any sanitation was done in between the editing. Thank you for the informative video.

hi, thank you for the video. If I want to determine the mechanical properties of PCB with copper layers in it, can we use three point bend test? for example, if I have a 4 layer 100mm X 100mm PCB of 1.6mm thick with different percentage of copper in each layers, how to find the properties like 'E' value? Is there any other method to find the properties without damaging the PCB since the PCBs will be different for different applications. we need to know this since copper increases the stiffness of the PCB.

Hi, how do we get the flexural modulus?
