ASCE has honored Yonggang Huang, Ph.D., M.ASCE, NAE, with the 2018 Zdeněk P. Bažant Medal for pioneering work on macro-, micro-, and nanoscale fracture, and application to transfer printing.
Huang is an internationally recognized leader in the area of failure and damage prevention. He has contributed significantly to the advancement of failure and damage theory and research in key areas across multiple scales, including macroscale, microscale, and nanoscale. At the macroscale, he is the first to develop the analytic model of intersonic crack propagation along the bimaterial interface, as well as the analytic model of intersonic fracture in fiber-reinforced composite materials. These models address many fundamental yet unanswered questions raised from the experiments, which for some time had puzzled the community of dynamic fracture.
At the microscale, he is the first to use the continuum mechanics model solving the puzzle of “cleavage cracks” in ductile materials observed in experiments, which had long puzzled the mechanics community. At the nanoscale, he has developed a nanoscale continuum theory based on the interatomic potential such that fracture becomes an integral part of the constitutive model – i.e., there is no need for a fracture criterion once the interatomic potential (therefore the constitutive model) is known. He has successfully applied fracture mechanics to transfer printing, which is a powerful manufacturing/fabrication method for semi-conductor technology.
Huang’s research seeks to integrate the disciplinary fields of mechanics and materials science by developing a clear understanding of the hierarchy of size scales that govern fracture of materials. The implications of his research range from improving the structural integrity in the automotive and aerospace industry, to designing components in micro-electronic industry, to developing nanotechnology.
The award may be made in even-numbered years to an individual whose career demonstrates significant contributions to the engineering science of failure and damage prevention in the form of a scientific paper, book, patent, or other form of scientific invention.
