Background

Professor K. Y. Lin received his undergraduate degree in 1969 from National Taiwan University in Taipei, Taiwan. He obtained his Masters in 1973 and Ph.D. degrees in 1977 from the Aeronautics and Astronautics Department, Massachusetts Institute of Technology, specializing in Aeronautical Structures and Composite Materials.  After graduating from M.I.T., he spent over six years in industry, working for Deere & Co. and The Boeing Company in the areas of composite materials, finite element methods, and fracture mechanics. Since his appointment to the University of Washington faculty in 1984, he has developed an extensive research program in aerospace composite materials. He has been awarded numerous research grants and contracts in composite materials from FAA, NASA, DoD, and The Boeing Company. Prof. Lin has co-founded the FAA Center of Excellence for Advanced Materials in Transport Aircraft Structures (AMTAS). Recently, in partnership with Boeing LTD, Prof. Lin has developed an award winning certificate program in Aircraft Composite Structural Analysis and Design at the University of Washington.  The program provides working engineers with state-of-the-art training in analysis tools and design methodology necessary to develop aerospace composite structural hardware.  In addition to his research endeavors, he has concentrated his teaching on the subjects of mechanics of composite materials, foundation of solid mechanics, and finite element methods. Prof. Lin has twice received Professor of Year awards from the Aeronautics and Astronautics students for his excellence in teaching and research in composite materials..

Research Activities

Professor Lin has co-developed a well-known Mar-Lin Fracture Model, which is being used by the aerospace industry for the damage tolerant design of composite aircraft structures. He has also developed a singular finite element method for the accurate analysis of bi-material fracture problems.  His current research topics include development of reliability-based damage tolerant structural design methodology, time-dependent fracture, as well as aging degradation of polymeric composites at elevated temperatures.  Most of his current research efforts have direct applications to the critical technologies needed in developing the next generation of aerospace vehicles.
