Regular (harmonic, subharmonic and quasi-periodic) and irregular (chaotic) oscillations appear depending on the system parameters as well as initial and boundary conditions. In order to achieve highly reliable results, an effective algorithm has been applied to convert a problem of finding solutions to the hybrid type partial differential equations (the so-called von K\u00e1rm\u00e1n form) to that of the ordinary differential equations (ODEs) and algebraic equations (AEs). The obtained equations are solved using finite difference method with the approximations 0(h<jats:sup>4<\/jats:sup>) and 0(h<jats:sup>2<\/jats:sup>) (in respect to the spatial coordinates). The ODEs are solved using the Runge\u2013Kutta fourth order method, whereas the AEs are solved using either the Gauss or relaxation methods. The analysis and identification of spatio-temporal oscillations are carried out by investigation of the series w<jats:sub>ij<\/jats:sub>(t), w<jats:sub>t,ij<\/jats:sub>(t), phase portraits w<jats:sub>t,ij<\/jats:sub> (w<jats:sub>ij<\/jats:sub>) and w<jats:sub>tt,ij<\/jats:sub>(w<jats:sub>t,ij<\/jats:sub>, w<jats:sub>ij<\/jats:sub>) and the mode portraits in the planes w<jats:sub>x,ij<\/jats:sub>(w<jats:sub>ij<\/jats:sub>), w<jats:sub>y,ij<\/jats:sub> (w<jats:sub>ij<\/jats:sub>) and in the space w<jats:sub>xx<\/jats:sub>(w<jats:sub>x,ij<\/jats:sub>,w<jats:sub>ij<\/jats:sub>), FFT as well as the Poincar\u00e9 sections and pseudo-sections. <\/jats:p>","DOI":"10.1142\/s021812740200525x","type":"journal-article","created":{"date-parts":[[2002,10,1]],"date-time":"2002-10-01T20:05:06Z","timestamp":1033502706000},"page":"1465-1513","source":"Crossref","is-referenced-by-count":30,"title":["SPATIO-TEMPORAL CHAOS AND SOLITONS EXHIBITED BY VON K\u00c1RM\u00c1N MODEL"],"prefix":"10.1142","volume":"12","author":[{"given":"J.","family":"AWREJCEWICZ","sequence":"first","affiliation":[{"name":"Department of Automatics and Biomechanics, Technical University of Lodz, 1\/15 Stefanowski St., 90-924 Lodz, Poland"}]},{"given":"V.
