Abstract
Method for layered structure breaking strength estimation in which an edge of a cutting blade is inserted into an upper layer of the structure and the cutting blade is moved substantially in parallel with an interface between the upper layer and a lower layer of the structure while automatically controlling a depth of the cutting blade to a depth slightly higher than the interface. A force exerted on the cutting blade substantially in parallel with the interface is measured. An apparatus for performing the method is also disclosed.
