Optimization Method for Acquiring High Resolution Mapping of Elastic Moduli
نویسندگان
چکیده
Recently, a new technique has been developed, which allows quantitative nanoscale mapping of elastic moduli by means of a hybrid nanoindentation and force modulation instrument. We introduce a procedure for finding the experimental parameters that provide an optimal modulus contrast. Application of the procedure on three different material systems demonstrated the technique’s capability to resolve between regions with elastic moduli as close as 5%. Thus, the improved modulus mapping procedure can be applied not only to composite materials but also to many multi-phase and multi-domain material systems.

متن کاملOptimization of Conformal Mapping Functions used in Developing Closed-Form Solutions for Underground Structures with Conventional cross Sections
Elastic solutions applicable to single underground openings usually suffer from geometry related simplification. Most tunnel shapes possess two axes of symmetry while a wide range of geometries used in tunneling practice involve only one symmetry axis. D-shape or horse-shoe shape tunnels and others with arched roof and floor are examples of the later category (one symmetry axis). In the present...
