Bending Module 200 to 5000 N For 3- and 4-Point-Bending (Top view)
Description
This deformation device was originally designed to fit underneath the cantilever of an AFM.It is manufactured high-vacuum compatible, so you may also use it in the SEM. Changing from a 3-point bending to 4-point bending is a matter of a few seconds, just exchanging the “anvil” on which the specimen rests in center. The specimens should be 35 to 50 mm long, no wider than 10 mm, and up to 4 mm thick. The design is based upon two important thoughts: the whole device is extremely rigid,
therefore almost no intrinsic flexure is detectable. Another advantage is the ultra-fine movement resolution of the load frame. Both these features are important with very brittle specimens, such as ceramics: after the finest initial cracks have formed, the specimen will not fly apart spontaneously. The bending process can be continued slowly, with extraordinary well defined load increase.
Applications:
Static or dynamic observations of surface changes under controlled mechanical load; crack growth, delamination phenomena, formation of slip planes etc. Metals, ceramics, glass, ceramic bulk materials or layers, galvanic coating, soldered or welded joints, minerals, wood, organic materials
