摘要
应用突变理论的尖点突变模型分析塑性粘土的蠕变性能,建立了简单的位移~剪应力~时间(λ~τ~t)关系.该尖点突变模型能够较好地描述材料的衰减和非衰减蠕变性能,且能够描述后者中的急剧破坏阶段.实例证明,该模型与试验结果吻合较好.
In this paper an analysis of creep rule for plastic clay by the cusp catastrophe model is presented.A simple relation of displace-ment ,shear stress and time (λ~τ~t)is established.It can express decay and non-decay creep performance of material and failure stage.The test data is given in the end.
