DEFORMATION CHECKING DEVICE AND METHODS OF ITS USE IN MECHANICAL STRUCTURES SUBJECTED TO STRESS

摘要

FIELD: measurement technology. SUBSTANCE: sensing element made of material the physical properties of which change during deformation is positioned on construction element. Material changing its phase state during deformation is used as sensing element material. After construction element is exposed to force or subjected to loading, phase variation value of sensing element is measured, and measurement result is used for determination of deformation value. EFFECT: higher measurement accuracy. 16 cl, 27 dwgc
