Stability of solitary waves for a rod equation. (English) Zbl 1046.35094
Summary: We consider a new rod equation derived recently by {\it H.-H. Dai} [Acta Mech. 127, No. 1--4, 193--207 (1998; Zbl 0910.73036)] for a compressible hyperelastic material. We prove that the smooth solitary waves to this rod equation are orbital stable.
