Colombia plants. The aim was to study detachment of fruits subjected to mechanical vibrations. A model of the coffee fruit\u2013peduncle system is designed computationally to reproduce its topology in all ripening stages using a proposed numerical procedure. Young\u2019s modulus, Poisson ratio, and density were adjusted using analytical models for all ripening stages. The glomerulus of three fruits in different ripening stages was proposed and these were combined in four groups. Based on a detachment model, it was verified which fruit was detached first when a chirp force signal was applied on each glomerulus. Results indicated that dynamic excitations applied in between 130 to 150 Hz detached only ripe fruits, since fruits that were in other ripening stages were not stimulated until detachment in that bandwidth.<\/jats:p>","DOI":"10.1177\/0037549717738068","type":"journal-article","created":{"date-parts":[[2017,10,25]],"date-time":"2017-10-25T10:16:12Z","timestamp":1508926572000},"page":"163-174","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":10,"title":["Harmonic stress analysis on\n                    <i>Coffea ar\u00e1bica L.<\/i>\n                    var.\n                    <i>Colombia<\/i>\n                    fruits in order to stimulate the selective detachment: A finite element analysis"],"prefix":"10.1177","volume":"94","author":[{"given":"Hector A","family":"Tinoco","sequence":"first","affiliation":[{"name":"Experimental and Computational Mechanics Laboratoy, Universidad Aut\u00f3noma de Manizales (UAM), Manizales-Caldas, Colombia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fabio M","family":"Pe\u00f1a","sequence":"additional","affiliation":[{"name":"Experimental and Computational Mechanics Laboratoy, Universidad Aut\u00f3noma de Manizales (UAM), Manizales-Caldas, Colombia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2017,10,25]]},"reference":[{"key":"bibr1-0037549717738068","unstructured":"FNC (Federaci\u00f3n Nacional de Cafeteros de Colombia).
