ASTM D790 (Flexural Properties)

ASTM D790 is a standardized test that measures how much a material, like plastic or composite, can bend without breaking. It evaluates the material’s flexural strength (maximum stress it can withstand when bent) and flexural modulus (stiffness or resistance to bending). During the test, a specimen is placed on two supports and a load is applied at the center until it bends or breaks. The results help determine the material’s ability to perform under bending forces, informing engineers about its suitability for applications where it will experience bending stresses.
