Abstract

A simple three-dimensional orthorhombic model of particles with displacive degree of freedom interacting with the strain variables has been studied by molecular-dynamics technique. The modulated degree of freedom is coupled linearly to the shear and bilinearly to the bulk deformation component. The computer simulation has confirmed that the commensurate 1 3 - incommensurate phase transition mechanism relies in nucleation and growth of stripples build up from six domains of commensurate phase 1 3, separated by discommensurations. A method of visualizing the discommensurations in a modulated pattern is proposed.
