Integrated experimental and computational system for the nondestructive determination of the mechanical properties of materials in situ in the oil, gas and petrochemical industry

摘要

This application discloses an experimental and computational system, with the relative method, for the non - destructive determination of parameters which quantify the mechanical, elastic and/or inelastic properties of structural materials or of tensional states in structural and plant components for structural diagnosis "in situ" preferably in industrial oil, gas and petrochemical fields, comprising:- an experimental subsystem containing: - a portable instrument suitable for indenting with a tip, the surface of said components for the production in situ of an imprint, on the surface of the structural or plant component; - a portable roughness meter suitable for revealing both the roughness of the surface and the geometry of the imprint. - a computational subsystem comprising a software suitable for generating functions which better represent the combination of points revealed with the roughness meter, a software for the simulation of mechanical phenomena involved in the production of said imprint, a software for the application of inverse analysis methods to the experimental data, and an auxiliary software with mathematical instruments suitable for accelerating the inverse analysis operations.
