ABSTRACT

This papers addresses the behaviour of hypoplastic equations near the reference configuration. By an approximation process, a general small􀀁strain hypoplastic equation is derived. Two particular equations are examined. It is shown that they can represent solids exhibiting different Young's moduli in compression and in extension.
