Understanding the concept of “pure bending”: it’s a method used to measure bending rigidity without applying shear force (which arises due to gravity).
The bending testing machines available on the market measure the deflection caused by gravity.
Kato Tech’s pure bending tester is unique in its ability to measure bending rigidity, defined by consistent curvature distance, rate, force, and speed.
This bending formula was invented by Professor Sueo Kawabata at Kyoto University in the 1970s.
The intricate mechanical techniques to detect microscale areas, coupled with a unique algorithm correlating measurement data with sensory evaluation, collectively led to the creation of the pure bending tester.
Detection of these microscale forces relies on an internally crafted Torsion Wire. This wire plays a crucial role by twisting at a constant speed and detecting the bending properties.
