This standard covers guided bend testing of welds for the determination of reliability and ductility in ferrous and nonferrous products.
The guided bend test is performed by placing a rectangular specimen symmetrically on the support fixture that is mounted to the testing machine. The load is applied to the weldment of the flat specimen at mid-span until the specimen conforms to a U-shape, or until failure occurs. After the bending test is completed, the curved surface of the bend is examined for evidence of a crack or surface irregularities to determine if the material has failed.
Solutions for ASTM E190 guided-bend test typically include these types of components:
MTS offers electromechanical Criterion® and Exceed® universal test systems and dynamic servohydraulic Landmark® test systems that are ideal for performing accurate and repeatable monotonic bend testing of metallic materials per ASTM E190.
MTS Criterion universal testing systems are engineered to support the needs of advanced Research & Development. MTS Exceed universal testing systems are best suited for Quality Control testing by delivering the reliable performance needed to meet the uptime demands of high-volume production environments. Due to the large variety of ferrous and nonferrous metals and specimen dimensions that can be tested per ASTM E190, the required force capacities can differ significantly. MTS offers frame models that address the smaller force requirements of thinner specimens up to high-force requirements for testing thick plate type specimens.
The MTS Criterion and the MTS Exceed universal testing machines range from tabletop to floor-standing electromechanical models with force ratings of up to 600 kN / 135 kip. Many of the models have dual-zone test spaces to reduce set-up times if you frequently change test requirements.
The MTS Landmark dynamic servohydraulic test system with its superior stiffness and alignment capabilities, is an ideal choice if additional fatigue and fracture testing capabilities are required. Systems are available in highly configurable floor-standing and tabletop models with force ratings from 5 kN / 1 kip to 500 kN / 110 kip.
As an alternative to a new load frame, you can replace outdated controls / hydraulics of existing MTS or another manufacturer’s electromechanical, servohydraulic or custom test systems, including: **Instron®, **Zwick®, **Tinius Olsen™, **SATEC®, **Baldwin® and more with an MTS ReNew™ Upgrade.
