    摘要： Fatigue failure in composite materials can be successfully modeled and predicted by monitoring irreversible gains in entropy. Permanent degradations in composites are marked by irreversible processes that are characterized by increases in entropy. By measuring changes in entropy, one can model and predict the deterioration and failure of composites. The technique may be used to predict the deterioration and failure of composites under essentially any type of loading—constant, variable, bending, torsion, tension, compression, or other.

    摘要： An interconnect sensor for detecting delamination due to coefficient of thermal expansion mismatch and/or mechanical stress. The sensor comprises a conductive path that includes a via disposed between two back end of line metal layers separated by a dielectric. The via is coupled between a first probe structure and a second probe structure and mechanically coupled to a stress inducing structure. The via is configured to alter the conductive path in response to mechanical stress caused by the stress inducing structure. The stress inducing structure can be a through silicon via or a solder ball. The dielectric material can be a low-k dielectric material. In another embodiment, a method of forming an interconnect sensor is provided for detecting delamination.

    摘要： The adherence of an individual fibre embedded in a polymer matrix is determined by a drawing experiment in which the fibre is drawn out of the polymer matrix and simultaneously the pertaining force-distance diagram is registered. To this end a test sample consisting of the polymer matrix with the individual fibre embedded therein is manufactured by melting down a quantity of polymer present in granular or powder form on an object holder, the individual fibre is dipped into the molten polymer mass and the polymer mass is subsequently cooled down below the melting point. Subsequently the object holder with the test sample adhering thereto is brought into a force-distance measuring device, and the free end of the fibre is fixed to a chucking device moveable in the direction of the fibre. In the drawing experiment, the drawing force acting on the fibre is converted into corresponding electrical signals by the force transducer, and evaluated, and simultaneously the distance covered by the chucking device is converted into corresponding electrical signals by the distance transducer, and evaluated.

    摘要： The adhesion of cord or wire to the elastomer, rubber, or rubbery material is measured by exerting forces or loads collinear with the cords or wires such that one of the cords or wires is pulled from between a pair of cords. The three cords are embedded in a predetermined length of the elastomer. In a static test the opposing forces are exerted at a predetermined rate. In a dynamic test the opposing forces oscillate at predetermined frequency. Fixtures adapting an MTS high-speed oscillating tester are provided. The foregoing abstract is not to be taken as limiting the invention of this application, and in order to understand the full nature and extent of the technical disclosure of this application, reference must be made to the accompanying drawing and the following detailed description.
