A new approach to measure the elasticity modulus for ceramics using the deformation energy method

This paper presents an alternative method to measure the modulus of elasticity to traction, E , for relatively limited sample sizes. We constructed a measurement system with a Force sensor ( FS ) and a Rotation movement sensor ( RMS ) to obtain a relationship between force ( F ) and bending ( ΔL ). It was possible by calculating the strain energy and the work of a constant force to establish a relationship between these quantities; the constant of proportionality in this relationship depends on E , I and L . I and L are the moment of inertia of the uniform cross-section in relation to an oriented axis and length, respectively, of the sample for bending. An expression that could achieve the value of E was deduced to study samples of Y-TZP ceramics. The advantages of this system compared to traditional systems are its low cost and practicality in determining E .
