Young's moduli were measured in compression tests using partial unloading. Three different poling states (unpoled, parallel, and normally poled with respect to the load direction) were investigated. The Young's modulus was found to be variable during the mechanical tests and increased up to about 130-150 GPa. A simple description of the possible effects on Young's modulus is presented.
