THREE POINT BEND TEST FIXTURES

For Flex, Bend, and Fracture Toughness Bond Testing

5 kN Flexure Fixture Catalog no. 2810-400

The flexure fixture allows a variety of flexural and fracture toughness bond tests to be performed, including determination of flexural modulus, flexural strength and flexural yield strength. Easy to install, the 3-point fixture can be modified with an optional conversion kit to provide a 4-point bending conversion. Lower anvils are adjustable to accommodate specimens of different spans. Deflection of the specimen can be measured either through crosshead displacement, or for more precise measurement you can use a mid-span direct measurement plunger with a clip-on extensometer.

5 kN FLEXURE FIXTURE
Catalog no. 2810-400


3 Point Bend Test on Plastic Specimen


Principle of Operation

The specimen is supported on two precision machined anvils of a defined radius. The force is applied either centrally (3-point) or at a defined distance either side of the center (4- point). The support beam is graduated lengthways in metric units for accurate positioning of the anvils, equally spaced to the center line.


Features

  • Rated capacity 5 kN (500 kgf, 1,125 lbf)
  • 3-point flexure fixture with an optional conversion kit for 4-point loading
  • Conforms to ISO, ASTM, DIN, and many other standards
  • Fully adjustable span distance to suit a wide range of specimen sizes
  • Adjustable stops for specimen widths up to 50 mm (2 in) for precise alignment
  • Optional deflectometer plunger assembly
  • Rugged design for minimum maintenance
  • Temperature range: -100 to +350°C (-148 to +660°F)

Application Range

Type of loading: Static flexure, cyclic flexure tests
Specimen material: Plastics, metals, alloys, composites, ceramics and other materials
Specimen shapes: Strip, bar, components
Common standards: ASTM D790, ISO 178

Bending / Hemming Test Fixture to VDA 238-100: 2020
Catalog No. CP130604

The CP130604 fixture has a maximum force capacity of 20 kN and is designed specifically for tight radius bend testing of sheet metals in accordance with VDA 238-100. The punch radius, roller diameter, and roller distance are constrained to reduce lab-to-lab variability. This is especially important in automotive chassis and body components where stronger and thinner materials are increasingly used to meet lightweighting initiatives.
