Bend Testing

Bend Testing

A bend test also known as bend testing is a mechanical test used to measure stiffness and yield properties of a material or component.

Bend testing is a destructive testing process used on raw materials and/or machined specimens. Bending a sample can determine how a material reacts under pressure. This test can help determine a materials ability to resist cracking or other surface issues as force is applied during one continuous bend.

Results are then compared to applicable test standards, quality requirements, industry codes or customer specifications.

Dunlop NDT (DNDT) also utilizes bend testing to evaluate base materials and welder test coupons for qualification, certification and performance purposes. This is a valuable tool used in the welder qualifications and the welding industry.

 

RESULTS/PROPERTIES THAT CAN BE DETECTED WITH BEND TESTING

  • This test method is used to detect defects in weld materials and the ductility and bending ability of base materials.
 

TYPES OF MATERIAL THAT CAN BE TESTED WITH BEND TESTING

  • Bend Testing can be used on various metals and alloys.
  • DNDT performs Bend Testing in accordance with standards that include: ASTM E190, ASTM E290 and EN 910.
