The Poincar\u00e9 sections at near subharmonic resonance conditions exhibit finger-shaped chaotic attractors, similar to the strange attractor mapping of H\u00e9non and the ones found by Holmes in his study of chaotic resonances of a buckled beam. The number of such fingers are observed to increase as the barrier distance from the equilibrium is decreased. These chaotic states are interspersed with regimes of periodic behavior, with the periodicity being in accordance with well defined period adding laws. This study also focuses on the ordered behavior of the one-impact period-[Formula: see text] orbits around the higher subharmonics of the oscillator. <\/jats:p>","DOI":"10.1142\/s0218127420501114","type":"journal-article","created":{"date-parts":[[2020,7,14]],"date-time":"2020-07-14T07:55:29Z","timestamp":1594713329000},"page":"2050111","source":"Crossref","is-referenced-by-count":7,"title":["Bifurcations in a Pre-Stressed, Harmonically Excited, Vibro-Impact Oscillator at Subharmonic Resonances"],"prefix":"10.1142","volume":"30","author":[{"given":"Aasifa","family":"Rounak","sequence":"first","affiliation":[{"name":"Department of Applied Mechanics, Indian Institute of Technology Madras, Chennai, Tamil Nadu 600036, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0970-3795","authenticated-orcid":false,"given":"Sayan","family":"Gupta","sequence":"additional","affiliation":[{"name":"Department of Applied Mechanics, Indian Institute of Technology Madras, Chennai, Tamil Nadu 600036, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2020,7,10]]},"reference":[{"key":"S0218127420501114BIB001","doi-asserted-by":"publisher","DOI":"10.1063\/1.881047"},{"key":"S0218127420501114BIB002","volume-title":"Piecewise-Smooth Dynamical Systems: Theory and Applications","volume":"163","author":"Bernardo M.","year":"2008"},{"key":"S0218127420501114BIB003","doi-asserted-by":"publisher","DOI":"10.1006\/jsvi.1995.0329"},{"key":"S0218127420501114BIB004","doi-asserted-by":"publisher","DOI":"10.1115\/1.2901387"},{"key":"S0218127420501114BIB005","doi-asserted-by":"publisher","DOI":"10.1002\/cta.4490140405"},{"key":"S0218127420501114BIB006","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevE.60.2086"},{"key":"S0218127420501114BIB007","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevA.44.916"},{"key":"S0218127420501114BIB008","doi-asserted-by":"publisher","DOI":"10.1039\/c0cp02776f"},{"key":"S0218127420501114BIB009","doi-asserted-by":"publisher","DOI":"10.1016\/0378-4371(94)90174-0"},{"key":"S0218127420501114BIB010","doi-asserted-by":"publisher","DOI":"10.1088\/0305-4470\/17\/9\/015"},{"key":"S0218127420501114BIB011","doi-asserted-by":"publisher","DOI":"10.1016\/0960-0779(92)90012-C"},{"key":"S0218127420501114BIB012","doi-asserted-by":"publisher","DOI":"10.1016\/0375-9601(85)90685-1"},{"key":"S0218127420501114BIB013","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevLett.50.1637"},{"key":"S0218127420501114BIB014","doi-asserted-by":"publisher","DOI":"10.1126\/science.264.5155.70"},{"key":"S0218127420501114BIB015","doi-asserted-by":"publisher","DOI":"10.1143\/PTP.68.669"},{"key":"S0218127420501114BIB016","doi-asserted-by":"publisher","DOI":"10.1143\/PTP.69.403"},{"key":"S0218127420501114BIB017","doi-asserted-by":"publisher","DOI":"10.1142\/S0218127418300318"},{"key":"S0218127420501114BIB018","doi-asserted-by":"publisher","DOI":"10.1147\/rd.393.0283"},{"key":"S0218127420501114BIB019","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijmecsci.2012.09.012"},{"key":"S0218127420501114BIB020","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevLett.56.1522"},{"key":"S0218127420501114BIB022","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevLett.68.1586"},{"key":"S0218127420501114BIB023","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevA.36.1428"},{"key":"S0218127420501114BIB024","doi-asserted-by":"publisher","DOI":"10.1007\/s100530170257"},{"key":"S0218127420501114BIB025","doi-asserted-by":"publisher","DOI":"10.1088\/1742-6596\/23\/1\/014"},{"key":"S0218127420501114BIB026","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevE.57.402"},{"key":"S0218127420501114BIB027","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevLett.82.414"},{"key":"S0218127420501114BIB028","doi-asserted-by":"publisher","DOI":"10.1121\/1.1912047"},{"key":"S0218127420501114BIB029","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevLett.11.80"},{"key":"S0218127420501114BIB030","doi-asserted-by":"publisher","DOI":"10.1016\/0022-460X(83)90407-8"},{"key":"S0218127420501114BIB031","doi-asserted-by":"publisher","DOI":"10.1115\/1.3169068"},{"key":"S0218127420501114BIB032","first-page":"43","volume-title":"Int.
