This technology offers an integrated analytical, numerical, and computational methodology and hardware system which enables high-fidelity, full-field displacement and strain measurement along with constitutive material characterization of material specimens.
Using an innovative, digital imaging based, meshless, random grid method; the present invention offers improved accuracy and reliability over existing methods for boundary displacement and strain measurement. Additionally, this technology advantageously enables accurate material characterization.
Further, the development of a hardware system, consisting of a multiple digital camera fixture, is designed to mount on existing uniaxial testing machine for accurate measurement of boundary forces, displacement, and full-field strain measurement.
