Apparatus indenter a point which is adapted to be tested, a block of material

摘要

The apparatus has a holding and heating device (14) for a tip (16) and a holding and heating device for a block of material, and heating units (5) narrowly surrounding a lateral wall of an annular sheath (36) and being in thermal-conduction contact to the wall. Assembling units (7) assemble a rigid body and the units (5). The tip can be heated at a preset temperature equal to that of the block of material to be tested during a test. The holding and heating device for the material rests a force sensor (26) by a connection unit (24) under the form of a tubular element (28) in zirconium oxide. The annular sheath has a shape corresponding to that of the body, which is made of a heat conducting material. An independent claim is also included for a method for measuring effort measured by a tip on a block of material.
