SOME QUALITATIVE RESULTS IN THE LINEAR THEORY OF MICROPOLAR SOLID-SOLID MIXTURES

摘要

This paper deals with the linear theory of micropolar solid-solid mixtures. First, some existence, uniqueness and continuous dependence results are derived. Then, the propagation of plane waves is studied. There are possible four types of waves: longitudinal displacement waves, longitudinal microrotation waves, transverse displacement waves and transverse microrotation waves. A detailed analysis is presented for the longitudinal displacement waves and the longitudinal microrotation waves.
