Example of a bend test

Bend test machines are typically universal testing machines specially configured to evaluate material ductility, bend strength, fracture strength, and resistance to fracture. Bend tests tend to be associated with ductile metals and metal products. Bend test equipment and test procedures are similar to flexure test equipment. Flexure tests are commonly associated with brittle materials including plastics, polymers, composites, glass and ceramics. That said, bend test and flexure test terms are used interchangeably in the testing industry.

A bend tester is configured to your requirements by our application engineers with a three or four point bend test fixture, the correct controller, and a deflectometer if you would like to measure sample deflection directly and accurately. Due to our modular machine design, your bend test machine can also be equipped to perform other applications such as tensile, cyclic, shear, flexure, peel, and tear by adding appropriate fixtures.

Selecting a Bend Test Machine

Your first step to choosing the correct bend tester is to determine your specimen geometry, size and strength characteristics. Armed with this information our applications engineer can identify the test machine capacity needed to test your sample. We will also help you define which test attributes or results you want, so we can confirm load cell selection, and deflectometer requirements.

100 Series Modular Bend Test Machines

Type:
Electromechanical
Force:
10 kN (2,250 lbf)

100 Series Electromechanical Bend Test Machines are modular tabletop systems ideal for tensile tests requiring load capacities up to 10 kN (2,250 lbf). This affordable series includes five lightweight load frames and four actuators that deliver different force/speed capacities. We offer several choices of price/performance controllers and test software, and a selection of load cells from the full scale actuator rating down to sub-gram load levels. The 100 Series is our most flexible series, making them a popular choice.

300 Series High Force Bend Test Machines

Type:
Electromechanical
Force:
600 kN (135 kip)

As our most popular test machines, the 300 Series Electromechanical Bend Test Machines are the best choice for performing static compression applications at forces between 1 kN and 600 kN (225 lbf and 135 kip). These dual column testers are available in both tabletop and floor standing models which can perform a variety of other tests including Tensile, Bend, Bond, Flexural, Fracture, Peel, Shear, Tear, Stress Relaxation, and Short-term Creep tests.

420 Family Guided Bend & Tensile Test Hydraulic Fixtures

Type:
Manual Pump Hydraulic
Force:
50 ton

An alternative approach to using a universal test machine is to purchase a guided bend test machine designed for only your specific test requirements. For instance, our 420 Series bend ductility test equipment performs tests of metal plate specimens and welded ferrous and non-ferrous materials which are referred to as guided bend testers. A plunger forces the specimen into a 180° bend against rollers on a base and the force is generated manually, electrically or pneumatically. Another special bend test machine measures the ductility for electrical steel (ASTM A720).

600 Series High Force Hydraulic Bend Test Machines

Type:
Hydraulic
Force:
2 MN (450 kip)

600 Series High Force Hydraulic Bend Test Machines are the best choice for performing static tension applications when high force capacity is needed, such as testing metals and metal products. 600 Series test machines feature capacities between 300 kN and 2 MN (67,500 lbf and 450 kip). 600 Series test machines also perform compressive, bend, fracture, and shear tests. The standard model features large diameter columns and rugged components for superior frame stiffness and durability.
