MODE OF DEFINITION OF STRESSED-DEFORMED STATE OF MASSIF OF MATERIAL Russian patent published in 2008 - IPC G01N3/00 E21C39/00 

FIELD: invention may be used for definition of stressed-deformed state namely for definition of stage of development of deformed processes in massif of material (in mountain massif, in massif of engineering construction etc).

SUBSTANCE: technical result is provision of possibility of receiving heralds of destruction of massif of exploited material of different degree of urgency (from long-terms to shot-terms). Mode of definition of stressed -deformed state of massif of material includes selection of samples of material, their loading and exposition of herald of destruction of massif, moreover samples from massif are selected with boring of cores, they expose physical-mechanical characteristics of material and components of fields of tensions, after that samples are subjected to loading with observance of criteria of physical and geometric similarity in accordance with exposed physical-mechanical characteristics of material and components of field of tension. At that they fix longitudinal and transversal deformations no less than in three points along perimeter of central part of sample, moreover conclusion about character of deformed processes in massif is made on basis of exposed character of deformations of samples.

EFFECT: defines stressed-deformed state in massif of material.
