Inverse problems with the digital image correlation: approach and applications

Emanuele Sgambitterra, Fabrizio Niccoli

A viable approach to solve inverse problems in elasticity is proposed. It is based on regression algorithms to estimate materials and/or loading parameters by fitting the experimentally-evaluated displacement field to representative…

About Measuring the Stress Intensity Factor of Cracks in Curved, Brittle Shells

Siwen Cao, Andras A. Sipos

Most techniques of measuring the stress intensity factor (SIF) in the cracking process assume a crack in a planar medium. Currently, there is no effective approach for curved brittle shells, particularly for non-developable cases, i.e.…
