Abstract:In this paper the expansion theory of a circular hole in an infinite medium with different moduli in tension and compredon is established. Both the elastic and plastic analyses of the expansion of thehole are studied. The influences of elastic parameters on the stresses,displacements and the develop-ment of the yielding zone around the hole are also discussed.
Keywords:bimodulus elasticity  expansion of a circular hole  moduli in tension and compression
