專題講座Speakers

Experience 

Since 1987, he has been a faculty member at the Institute of Applied Mechanics, National Taiwan University, Associate Professor (1987) and Professor (1993), and has been appointed a distinguished professor since 2007. He was a three-time recipient of 科技部傑出獎 (Taiwan), and once the 講座 award from 傑出人才基金會. He had held several visiting positions at the renowned institutions: California Institute of Technology (Summer 1987), University Erlangen-Nu rnburg (1994-1995, Humboldt Research Fellow), University of California, Berkeley (Fall, 1997, NSC Visiting Program), Columbia University (Fall, 1998, Adjunct Professor), and HKUST (Hong Kong, Spring, 2003, Distinguished Visiting Scholar Program). From July 2005 to June 2009, Prof. Chang had held a joint appointment in Academia Sinica on mission to establish Division of Mechanics in the Research Center for Applied Sciences, then returned to NTU, serving as the Director of the Institute of Applied Mechanics (2009 08-2012 07). Professor Chang had also served as one of two Taiwan’s representatives to the General Assembly of IUTAM (International Union of Theoretical and Applied Mechanics) for 10 years, from 2010 to 2020.  

Fields of Research Interest 

Prof. Chang has done research works in the fields of fluid mechanics and scientific computation & experiemnts, specializing in vortex dynamics, unsteady flow and turbulence as well as two-phase suspension flow. In particular, he has developed the theory of force elements in hydrodynamics and aerodynamics, and recently proposed the concept and techniques of principal spectral analysis and spectral representation modes. Over the years, he has also been engaged in research on micro & nano-fluidics, biological modeling and imaging techniques as well as in mechanics of micro-scale composites, 2D materials (such as grapheme, boron nitride), photonic band-gap materials and nano-optics/plasmonics for metallic/dielectric materials, and more recently on self-cleaning surfaces, turbo molecular pump flow. He has published (co-authored) more than 150 papers in internationally renowned journals such as Physics of Fluids, Journal of Fluid Mechanics, Proc Royal Society, London, Series A, CARBON, Nanoscale, ACS Nano, Journal of Materials Chemistry A, Ultrasound in Medicine and Biology and Physics in Medicine and Biology. In the past 36 years, Prof. Chang has supervised 26 doctoral theses and over 140 theses for master degrees which cover a wide range of topics in Applied Mechanics, all in the National Taiwan University.

Abstract

Anisotropic and layered structures are ubiquitous: layered sediment rocks and layered global Earth as in nature, and laminated composites and layered quantum structures as manufactured or grown by human. In this talk, I will present the recent advances in modeling and simulation of these structures with application examples in mechanical/civil engineering. The new approaches to be presented have certain advantages as compared to the traditional ones. They are associated with: 1) the Stroh formalism in anisotropic elasticity for its mathematical elegance and computational convenience; 2) the new systems of vector functions, in terms of which, different deformation/wave features are closely correlated; and 3) the special propagation matrix methods for unconditional stable solution. The beautiful Love numbers will be also introduced for horizontally layered structures where they can be pre-calculated and saved for the corresponding Green’s function calculation. Applications examples are: 1) defects in layered smart composites and in poroelastic earth media; 2) waves in composites and in near-surface geotechnical media; and 3) interaction between superstructure and substrate/foundation, as relevant to material property calibration via indentation and soil-structure interactions in foundation engineering.

Ernian Pan obtained his BS and MS degrees from Lanzhou University and Beijing University, respectively, and his PhD from University of Colorado at Boulder. He joined the National Yang Ming Chiao Tung University in December 2021 as a Chair Professor after 18 years with the University of Akron in Ohio. His teaching and research are in continuum/computational methods/mechanics with applications in modern engineering and Earth science. These include pavement/earth deformation due to surface and internal loading/source, mechanical and electronic properties of quantum heterostructures, and magnetoelectric effect in multiferroic composites. He has a great passion on fundamental solutions and/or Green’s functions, particularly those in anisotropic and layered systems, and is always looking for collaborations in the related topics. He has published about 400 peer-reviewed journal articles, designed a couple of software products, coauthored a book in 2015 titled Static Green's Functions in Anisotropic Media by Cambridge University Press, and written a review paper in 2019 Rep. Prog. Phys. titled “Green’s functions for geophysics: a review”.
