Brown<\/strong>, assistant professor in mechanical engineering, was published in the <em>Journal of Applied Mechanics<\/em>. The research explored the mechanical behavior and design of simple interlocking structures and was conducted in collaboration with colleagues from the University of Colorado.<\/p>\n<p>Mechanical interlocking is the behavior that occurs when parts are assembled by sliding them together until they &ldquo;snap-through&rdquo; into a final position. Until now only a few types of interlocking joints could be modeled, but this paper expands the ability of engineers to design and analyze snap-together systems.<\/p>\n<p>The team started exploring this problem after <a href=\"https:\/\/doi.org\/10.1109\/JMEMS.2016.2519341\">earlier work in nanotechnology fabrication<\/a> led to its demonstration of surfaces that joined together by ultrasmall (less than 300 atoms thick) interlocking tabs.<\/p>\n<p>In the new paper, the team compared mathematical and computational models of a simple snap-together system and tested these models with an experiment. The results of this work demonstrated snap-through results from the geometry of a problem and that these systems can be designed to achieve at least a 50-times difference between the force required to press them together versus the force required to pull them apart.<\/p>\n<p>The team projects that, in addition to providing a basis for further work in large-deflection mechanics (the study of objects subject to a large amount of bending), the discovery will contribute to design of new part assembly mechanisms for manufacturing and medical materials. <\/p>\n<p>Some possible applications include ultrahigh temperature joints, medical adhesives, joining of dissimilar materials and assembly of complex or flexible parts.<\/p>\n<p>Brown joined the <a href=\"http:\/\/www.me.hawaii.edu\/\">Department of Mechanical Engineering<\/a> in August 2017.
