An alternative interpretation of nanoindentation experimental data and the associated phenomenon of indentation size effect (ISE) is proposed on the basis of a simple gradient elasticity equation. used to account for the development of elastic gradients generated by the geometry characterizing the indenter-specimen system. An application is considered for marble. i. http://www.pomyslnaszycie.com/western-321-cyl-reg-adaptor-cga-200-to-cga-510-online-sale/
