|Project's title||Research on ultrasonic waves in multilayered anisotropic structures, applications in nondestructive evaluation and material characterization|
|Research hosting institution||Graduate University of Science and Technology|
|Project leader’s name||Phan Hai Dang|
|Project duration||01/09/2020 - 30/09/2022|
|Project’s budget||408 million VND|
|Goal and objectives of the project|| |
- Theoretical study of ultrasonic wave propagation in anisotropic materials (for example transversely isotropic, orthotropic or general anisotropic)
|Main results|| |
- Theoretical research: the project successfully obtained closed-form solutions of wave motions in anisotropic layered structures under ultrasonic sources. As a result, several peer-reviewed journal papers are published and presentations are presented at international conferences
|Novelty and actuality and scientific meaningfulness of the results|| |
- Obtaning closed-form solutions of guided wave motions in anisotropic layered structures under time-harmonic sources is main contribution of the current project. We also calculate phase and group velocity dispersion curves superimposed by scattered amplitudes and obtain excellent agreement between analytical predictions and numerical results. These derivations are very important to solving inverse problems and developing practical applications in NDE and bone QUS.
|Products of the project|| |
- Scientific papers in referred journals (list):

The results obtained from this project were used in building experimental setup for measuring surface wave signals and improving the quality of data at Wave and Structural Health Monitoring Lab., Pusan National University.
As a principal investigator, I would like to sincerely thank to Postdoc program of Graduate University of Science and Technology (GUST) who provided us the grant to perform and obtain excellent results for this project. With the support, we successfully developed a new research direction in Vietnam. This Postdoc program is wondeful and significant to young scientists who have a strong desire in research work. For the principal investigator, this funding came in right time when I had new ideas for a breakthrough research direction but had not found a funding yet. The research team also thanks the coordinating unit, Institute of Mechanics, for creating all favorable conditions for the project to have a great success.
