This monograph presents the applying of soliton concept to unravel yes difficulties chosen from the fields of mechanics. The paintings relies of the authors’ study, and on a few particular, major effects latest within the literature. the current monograph isn't really an easy translation of its predecessor seemed in Publishing residence of the Romanian Academy in 2002. advancements define the best way the soliton idea is utilized to unravel a few engineering difficulties. The publication addresses concrete answer equipment of sure difficulties reminiscent of the movement of skinny elastic rod, vibrations of preliminary deformed skinny elastic rod, the coupled pendulum oscillations, dynamics of left ventricle, temporary move of blood in arteries, the subharmonic waves iteration in a piezoelectric plate with Cantor-like constitution, and a few difficulties relating to Tzitzeica surfaces. This entire learn allows the readers to make connections among the soliton actual phenomenon and a few partical, engineering difficulties.

11) Again, for a ( x, t ) exp(T1 ) , b( x, t ) exp(T2 ) , Ti ki x  Y i t  D i , i 1, 2 , it follows that B[exp(T1 ), exp(T2 )] [(k2  k1 )(Y 2  Y1 )  (k2  k1 ) 4 ]exp(T1  T 2 ). 12) suggest some forms to be chosen for the 3 functions f n , n t 1 . 10) are identically verified if f n { 0, n t 2 . Thus, we obtain f1 ( x, t ) 1  H exp(k1 x  k13t  D1 ) , u ( x, t )  k12 k x  k13t  D1  ln H sech 2 [ 1 ]. 15) leads to D1  ln H, k1 2 . 15) is given by the soliton wave u ( x, 0) 2sech 2 ( x  4t ) .

The first term Tlin represents, as above, a linear superposition of cnoidal waves. 23) gives n Tlin ¦D [K 2S l l 1 l qlk 1/ 2 f ml ¦ [1  q 2 k 1 l k 0 cos(2k  1) SZl t 2 ] ]. 39) l 1 with q exp(S S/2 K K (m)  ³ 0 K c(m1 ) Kc ), K du 1- m sin 2 u K (m), m  m1 , 1. The second term Tint represents a nonlinear superposition or interaction among cnoidal waves.

Next, we are going to investigate the stability of the KdV soliton with respect to wavefront bending, for example. The amplitude of the wave is calculated for a small perturbation of the argument T . If the amplitude remains constant, the soliton is stable. 6) f 1  exp(2[0 ) , [0 k0 ( x  Vt) . 25) Now assume the phase and amplitude of the KdV equation are slowly varying functions of y , perpendicularly to direction x . 26) 0. 25) as fˆ gˆ , fˆ f gˆ 1  exp(2[) , 1 g , [ k ( x  Vt) . 27), we obtain [( Dx Dt  Dy2  Dx4 )( fˆ , fˆ )]gˆ 2  fˆ 2 [( Dx Dt  Dy2  Dx4 )( gˆ , gˆ )]   6( Dx2 ( fˆ , fˆ ))( Dx2 ( gˆ , gˆ )) 0.
