摘要
本文研究了考虑损伤的蠕变介质的变形场与损伤场的解。求得了下列三个问题的新解:(1)考虑损伤的指数律蠕变材料在小损伤条件下的变形场与损伤场;(2)幂律蠕变材料在大损伤条件下的裂纹尖端场;(3)全耦合蠕变损伤的圆柱扭转问题的变形场与损伤场,这三个新解均可用解析的形式表达。
In this paper, the analytical solutions for the deformation-damage fields in creeping solids considering the damage effect are investigated. Three new solutions for
following topics have been deduced :(1) The deformation-damage fields for damaged medium with exponential creeping law under small damage condition; (2) Near crack-tip fields in damaged materials with power creeping law under severe damage conditions; (3) The stress-strain-damage fields of the coupling creep-damage problem of circular cylinder under torsional loading. All of the three new solutions have been expressed in closed form.
