| 摘 要： | 本文以冻结粉砂依赖于温度的峰值应力为判据,提出了一个能够考虑温度软化、应变率以反双曲正切关系依赖于过应力的弹粘塑本构关系。在一维的情况下,与常应力蠕变实验曲线符合较好。

| Abstract: | An elastic viscoplastic constitutive model is proposed.This model takes account of temperature soften and overstress depending on strain rate by antihyperbolic tangent form, as well as is judged by crest stress depending on temperature of frozen silt.In the case of one dimension, better agreement between the prediction of the proposed model and creep tests under constant stress is achieved. |
