Flexural Bend Testing

Flexural bend testing method measures the behavior of materials subjected to simple bending loads. Similar to elastic modulus in tensile testing, flexural modulus (stiffness) is the slope as determined by stress over strain in the elastic region of the force vs. deflection curve.

Flexural testing is commonly used on brittle materials such as ceramics, stone, masonry, some metals and glasses.  It can also be used to examine the behavior of materials which are intended to bend during their useful life, such as wire insulation, plastic tray materials and other elastomeric products.

DDL’s Product & Materials Division can carry out flexural testing to accepted industry standards, assist with the creation of custom protocols and create custom fixturing for special case needs.

A few of the standards that employ flexural testing include:

  • ASTM C393 – Flexural Properties of Sandwich Constructions
  • ASTM C1161 – Flexural Strength of Advanced Ceramics at Ambient Temperature
  • ASTM D648 – Deflection temperature of plastics under flexural load
  • ASTM D790 – Flexural Properties of Un-reinforced and Reinforced Plastics and Electrical Insulating Materials
