Compliant Mechanisms Howell Pdf: Fundamentals and Applications of Flexible Devices



In mechanical engineering, compliant mechanisms are flexible mechanisms that transfer an input force and displacement at one port to an output force and displacement at another port through elastic body deformation. These may be monolithic (single-piece) or jointless structures.

Geometric nonlinearities often complicate the analysis of systems containing large-deflection members. The time and resources required to develop closed-form or numerical solutions have inspired the development of a simple method of approximating the deflection path of end-loaded, large-deflection cantilever beams. The path coordinates are parameterized in a single parameter called the pseudo-rigid-body angle. The approximations are accurate to within 0.5 percent of the closed-form elliptic integral solutions. A physical model is associated with the method, and may be used to simplify complex problems. The method proves to be particularly useful in the analysis and design of compliant mechanisms.


Larry L. Howell is a professor and Associate Academic Vice President (AAVP)[1] at Brigham Young University (BYU). His research focuses on compliant mechanisms, including origami-inspired mechanisms, microelectromechanical systems, medical devices, space mechanisms, and developable mechanisms. Howell has also conducted research in lamina emergent mechanisms and nanoinjection.[2] He received a bachelor's degree in mechanical engineering from BYU and master's and Ph.D. degrees from Purdue University. His Ph.D. advisor was Ashok Midha, who is regarded as the "Father of Compliant Mechanisms."[3]


Howell joined the BYU faculty in 1994 and served as chair of the Department of Mechanical Engineering from 2001 to 2007 and as Associate Dean of the Ira A. Fulton College of Engineering from 2016 to 2019.[4] In addition to research, he has been a BYU AAVP since 2019.[1] Prior to joining BYU, he was a Visiting Professor at Purdue University, a Finite-Element Analyst for Engineering Methods, Inc., and he was an engineer on the design of the YF-22, the first prototype of the U.S. Air Force F-22 Raptor. His patents, technical publications, and research focus on compliant mechanisms, including origami-inspired mechanisms, space mechanisms, microelectromechanical systems, and medical devices. His research has been funded by the National Science Foundation, Air Force Office of Scientific Research, NASA, Department of Defense, and industry. He is the author of the book 'Compliant Mechanisms[5] and co-editor of the Handbook of Compliant Mechanisms, which are available in English and Chinese. His lab's work has also been featured in popular venues such as the PBS documentary program NOVA.


Compliant Mechanisms: Principles and Design. Instructor: Prof. G. K. Ananthasuresh, Department of Mechanical Engineering, IISc Bangalore. This course introduces the concept and principles of compliant mechanisms and presents the design methods in detail. Various applications of compliant mechanisms in consumer products, microsystems, aerospace, automotive, and biomedical industries will be touched upon throughout the course. It is a comprehensive treatment of the growing field of compliant mechanisms starting from the classics and basics and ending with the state of the art. (from nptel.ac.in) 2ff7e9595c
