碩士 === 國立中央大學 === 土木工程學系 === 105 === In last three decades, there are so many realated researchs about the mechanics problem of the incompressible material containing microporosity subjected to triaxial loading.Especially, the research published by John Ball in 1982 and the research published by Hou and Abeyaratne in 1992.It become a great challenge to obtain the analytical solution due to the problem possess no longer circular symmetry. Hou and Abeyaratne propose that the approximate solution is called Hou-Abeyaratne Field. The theme derivate the asymmetrical deformation of the ellipsoidal micro-void by importing the HAF, and use the principle of virtual work to derivate the corresponding matrix and draw the failure envelope of different ellipsoidal micro-void, and discuss the result.
