Abstract
The principles of operation and optomechanical design of novel optical extensometer OPEX for tensile testing machines is presented. The system provider on-line strain measurements performed at an arbitrary measurement base. OPEX is integrated with a tensile loading machine so it can be used for active controlling of the machine setup. The applicability of the system is demonstrated by determination of elongation of various mechanical samples subjected to uniaxial tensile tests.
