Abstract: A method includes obtaining failure initiation characteristics of a bonding layer of one or more bonded structures and determining, based on the failure initiation characteristics, a first characteristic dimension for each analysis element of a first portion of a finite element analysis model. The method includes obtaining failure propagation characteristics of the bonding layer and determining, based on the failure propagation characteristics, a second characteristic dimension for each analysis element of a second portion of the model. The method includes assigning a first set of material parameters to analysis elements of the first portion of the model and assigning a second set of material parameters to analysis elements of the second portion of the model. The method includes evaluating failure modes of the one or more bonded structures based on a solution to the model, the first set of material parameters, and the second set of material parameters.

Abstract: A method and apparatus for analyzing an object using acoustic emissions. Load data is received for the object. Acoustic waveform data is received for the object from an acoustic sensing system. The acoustic waveform data represents acoustic emissions emanating from the object and is detected using the acoustic sensing system. A plurality of bins is created for the load data. A plurality of frequency distribution functions is generated for the plurality of bins using the acoustic waveform data. A set of learning algorithms is applied to the plurality of frequency distribution functions and the acoustic waveform data to generate an output that allows an operator to more easily and quickly assess a structural integrity of the object.

Abstract: A holder for attaching an acoustic emission sensor to a non-metallic and non-magnetic material has a tubular body with a closed top end and an open bottom end through which the sensor is insertable into the tubular body. The closed top end has a plurality of unitary flexible flaps angularly extending inwardly from an inner surface of the enclosed top end. An inner surface of the tubular body has a plurality of spacers extending radially inward proximate the bottom end of the tubular body. The unitary flexible flaps and the spacers fix the sensor within the tubular body. The tubular body may also have a plurality of capture tabs extending outwardly from an exterior surface thereof proximate the open bottom end that are slidably and removably engageable with an engagement keyway in a retainer bracket that is affixed to a non-metallic and non-magnetic material.

Abstract: An example method includes determining analytical material properties indicative of an effective fracture behavior of a through-thickness reinforcement. The method also includes obtaining data defining a cohesive formulation within a finite element analyzer. The cohesive formulation is representative of the through-thickness reinforcement, and the data defining the cohesive formulation is derived from the analytical material properties. The method further includes generating a finite element model for the composite structure. The composite structure includes the through-thickness reinforcement, and the finite element model represents the through-thickness reinforcement using the cohesive formulation. The method also includes analyzing a mechanical performance of the composite structure using the finite element analyzer and the finite element model, and outputting data indicative of the mechanical performance of the composite structure.

Abstract: An example method includes determining, by a computing system, a dry thickness of a fabric preform. The method also includes determining, by the computing system, a debulked thickness of the fabric preform using the dry thickness of the fabric preform. In addition, the method includes determining, by the computing system, a stitch tension using the dry thickness of the fabric preform and the debulked thickness of the fabric preform. And the method includes causing, by the computing system, a stitching machine to apply a through-the-thickness stitch having the stitch tension to the fabric preform.

Abstract: A load frame for applying a tensile load to a test sample during a test or measurement includes a first gripper for gripping a first end of the test sample, a second gripper for gripping a second end of the test sample, and a tensioner for applying the tensile load to the test sample. The load frame further includes a first end tube that encircles the first gripper, a second end tube that encircles the second gripper, and a center tube that encircles a mid-portion of the test sample during the test or measurement. A system such as a wave-generating system may be used to measure the test sample through the center tube during a test or measurement.
