Dr. Yuan-Cheng “Bert” Fung: The Father of Biomechanics

Dr. Yuan-Cheng “Bert” Fung is a renowned scientist, whose groundbreaking work has influenced multiple fields, including biomechanics, aeronautics, and bioengineering. As an Asian-American, Fung’s accomplishments have paved the way for future generations of scientists from diverse backgrounds. This article explores the life and work of Dr. Fung, highlighting his significant contributions to the scientific community.

Born in 1919 in Jiangsu Province, China, Fung was a bright student with an affinity for mathematics and physics. He earned his Bachelor’s and Master’s degrees in Aeronautical Engineering from the National Central University (now known as Nanjing University) in China. Fung later moved to the United States to pursue his doctorate at the California Institute of Technology (Caltech), where he obtained his Ph.D. in Applied Mechanics in 1948. Despite facing language barriers and cultural differences, Fung excelled in his studies and research, reflecting his determination and resilience.

Dr. Fung began his professional career as a research engineer at the California Institute of Technology’s Jet Propulsion Laboratory. His work there focused on aircraft structures and materials, which led to significant contributions to the understanding of aeroelasticity, the study of how an aircraft’s structures respond to aerodynamic forces.

In the 1950s, Fung’s research interests pivoted to the field of biomechanics, after an encounter with a physician who asked him to investigate the mechanical properties of blood vessels. This marked the beginning of his pioneering work in the field, which ultimately earned him the title “Father of Biomechanics.”

Dr. Fung was a professor at the University of California, San Diego (UCSD), where he founded the Bioengineering Department in 1966. His research at UCSD led to groundbreaking discoveries in the fields of tissue engineering, cellular mechanics, and the mechanics of blood flow. Fung’s work helped advance the understanding of the mechanical properties of living tissues, bridging the gap between biology and engineering.

One of his most significant contributions was the development of the “constitutive equation,” a mathematical description that relates the stress and strain of soft biological tissues like skin, blood vessels, and organs. This equation has become a cornerstone in biomechanics, allowing scientists and engineers to predict how tissues will respond to various forces and conditions.

Fung’s constitutive equation is a mathematical description that establishes the relationship between the stress and strain experienced by soft biological tissues, such as skin, blood vessels, and organs. It accounts for the complex and nonlinear behavior of these tissues, which is a crucial aspect for understanding their mechanical properties.

The development of the constitutive equation enabled scientists and engineers to predict and analyze how living tissues respond to various forces and conditions, opening up new possibilities for research and practical applications. It has been instrumental in advancing the fields of tissue engineering, injury prevention, and the development of medical devices, such as artificial organs and prosthetics.

In addition to his research, Fung was a prolific author and wrote several seminal textbooks, including Biomechanics: Mechanical Properties of Living Tissues and Biodynamics: Circulation. These texts have become foundational resources for students and researchers in the fields of biomechanics and bioengineering.

Throughout his career, Dr. Fung received numerous awards and honors, including the National Medal of Science in 2000, presented by then-President Bill Clinton. Fung was also elected to the National Academy of Engineering and the National Academy of Sciences, as well as being named an Honorary Fellow by the American Institute for Medical and Biological Engineering.

As an Asian-American scientist, Fung’s accomplishments have had a significant impact on the representation of Asian-Americans in the field of science. His perseverance and dedication to research have inspired countless others to follow in his footsteps, fostering a more diverse and inclusive scientific community.
