Abstract: Both rate dependent and gradient-dependent models introduce internal length scales in dynamic initial value problems.The paper studies strain localization and stability of material by simple harmonic motion for rate dependent and gradient-dependent models. The laws of internal length scales and conditions of material stability are obtained at two dimensions condition for two mixture models. And more, formula of strain localization band width at the one and two dimensions conditions is derived.

Key words: strain localization, Internal length scales, rate dependent and gradient-dependent models
