Notizen:
For strain-softening materials with different elastic modulus of tensile compression, twocontrolling parameters were introduced to take into account the different modulus and strainsofteningproperties. By means of twin shear unified strength theory, unified solutions calculatingstress and displacement fields of expansion of cylindrical cavity were derived. The effects causedby different elastic modulus in tensile and compression, different models and strain-softening rateson stress and displacement fields, development of plastic zone were analyzed. The results show theultimate expansion pressure, stress and displacement fields and development of plastic zone varywith the changes of different elastic modular, different models and strain-softening properties
