Flexural Strength of Advanced Ceramics at High Strain Rates. This is a Dynamic testing standard often used for defense applications (ballistics). It requires strain rates significantly higher than standard quasi-static machines can provide. Testing is usually performed on a High-Rate Servo-Hydraulic system or a Drop Tower. The technical commentary here focuses on Signal Processing. At high speeds, the Inertial Load (the force required to move the fixture itself) can be higher than the specimen’s failure load. MTO’s high-rate systems utilize piezoelectric load cells and Inertial Compensation algorithms to filter out the mechanical noise of the fixture, providing a clean record of the ceramic’s high-speed fracture toughness. This is a niche, high-spec lead that requires an Engineer-to-Engineer deep dive into frequency response and data aliasing.
