Introduction
MTS Series 642 Bend Fixtures test the flexural bending properties of specimens.
The grips are suited for fracture toughness tests (ASTM E-399), plastics tests
(ASTM D-790, flex test), and composites tests (ASTM D-2344, short beam
shear).
Note
This manual covers the Model 642.001, 642.01A, 642.10B, and 642.25
Bend Fixtures, all of which have the same basic components. The
illustrations on most of these pages show only the Model 642.10B, but
the information provided applies to all four models. Where differences
occur among the different models, these will be pointed out. Model-
specific illustrations are also included where appropriate.

Series 642 Bend Fixture Functional Description
The bend fixtures have an upper and lower bedplate that attach to your load unit’s
force transducer and actuator with cap screws. The Model 642.001, 642.01 and
642.10 bend fixtures attach directly to the actuator and force transducer, while
the Model 642.25 Bend Fixture uses an adapter plate to attach to the actuator and
force transducer.
Adjustable roller block assemblies slide back and forth in the bedplates, giving
you different loading spans. The bedplates have scales, in metric and US units,
for accurately adjusting the loading spans.
