概要: This paper examines the diffuse bifurcation mode of a hollow circular cylinder specimen consisting of a non-coaxial Cam- clay model. The specimen undergoes a non-axisymmetric deformation by a prescribed velocity with no friction on the ends and a constant lateral hydrostatic pressure on the side. We obtain several bifurcation loads and examine the sites where the slip planes first occur from the maximum shear strain point of view.<br />出版者照会後に全文公開 続きを見る

概要: This paper examines the diffuse bifurcation mode of a two-layer specimen consisting of a non-coaxial Cam-clay model. The specimen undergoes a deformation by a prescribed velocity with no friction on the ends and a constant lateral hydrostatic pressure on the sides. We obtain several bifurcation loads and examine the effect of several material parameters on the bifurcation load. We finally investigate the sites where the slip planes first occur from the maximum shear strain point of view. 続きを見る

概要: This paper examines the influences of the aspect ratio on the bifurcation analysis for a non-coaxial and a coaxial Cam-clay model of normally consolidated clays during undrained shear under plane strain condition. The bifurcation analyses are carried out considering the difference between the aspect ratio at the onset of bifurcation and the initial aspect ratio. As a result, we show the existence of the symmetric bulging mode, which is often observed in the experiment. We also examine the sites where the slip surfaces first occur and the patterns of the slip surfaces by judging from the distributions of maximum shear strain. 続きを見る
