Abstract:
Sensor for measuring force and strain in solid materials, designed to be inserted in axial direction in a bore within a solid material, comprising:an outer part suited to be inserted in said bore and having a multi-angled outer surface so as to touch the bore of the sold material with axial line-like contact ridges, the outer part being slotted in an axial direction alternately from both axial ends of the outer part so as to allow an expansion of the outer part for adapting its periphery to the bore, and having an inner periphery conical in the axial direction, an inner part having a correspondingly conical outer periphery so as to allow the inner part to be pressed axially into the outer part so that the corresponding conical inner periphery of the outer part and the outer periphery of the inner part contact against each other, and measuring sensors fixed to the inner side of the inner part sensing forces and strains of the inner part resulting from corresponding forces and strains within the solid material.
