摘要
概括近几年国内外蠕变力学领域的研究进展,阐述了理论、试验等方面已经取得的成果,着重介绍了有限元计算机模拟,并通过工程实例进行了索膜结构蠕变的有限元分析,描绘出了理想的蠕变曲线,得出一些有用的规律,为考虑蠕变影响的应力应变分析提供了科学依据。
The study progress in creep mechanics domain in recent years at home and abroad is summarized, Accomplished achievements in theory and experiment is expatiated on, finite element computer simulation and engineering example analyses of creep performance of cable-membrane structure are emphasized and perfect creep curve is described, some useful rules are educed , which provides science foundation of stress-strain analysis for considering creep affect.
