Determination of elastic and flexural strength properties of multi-scale materials via indentation assisted micro-bending experiment and inverse analysis

An original approach for mechanical characterization was developed using indentation assisted micro-bending. Aiming at the reliable measurement of elastic modulus multi-scale solids, technique relies on deflection measurements cantilever-type beams modeled within framework foundation. The inference is carried out by postulating inverse problem and solving it via error minimization approach. validation performed a set reference materials disclosed proposed technique's potential accurate properties flexural strength micro mesoscale, motivating its extension to heterogeneous - cementitious composites in particular. • instrumented micro-bending has been developed. beam Winkler-type foundation model used as representation. Multi-variable estimation properties. Validation construction materials. methodology successfully applied systems.
