FIELD: investigation of stress-deformed state of artificial structures at testing process. SUBSTANCE: method comprises steps of mechanically unloading selected portion of object, measuring residual deformations of said portion for detecting degree of mechanical unloading due to change of reaction of separated portion to testing stimulus before and after unloading. Inner stresses are detected according to residual deformations while taking into account degree of mechanical unloading with use mathematical relation. EFFECT: enlarged using range, enhanced accuracy and simplification of method. 3 cl, 2 dwg
