Apparatus And A Method For Measuring In-Plane Elastic Constants For A Laminate |
摘要 |
An apparatus is provided that includes a wave generator, plurality of transducers and processing device. The wave generator may be configured to simultaneously generate a plurality of acoustic waves that propagate through a laminate along a plurality of in-plane directions. The transducers may be spaced apart from one another and positionable at one or more known distances from the wave generator along respective in-plane directions. The transducers may be configured to detect acoustic waves propagating through the laminate along the respective in-plane directions. The processing device may be coupled to the transducers and configured to simultaneously calculate a plurality of elastic constants of the laminate as a function of velocities of the acoustic waves detected by the transducers. And the processing device may be configured to calculate the velocities as a function of the known distance(s) and arrival times of the acoustic waves at the transducers. |
