LCF life was decreased dramatically because of notch and acuity of notchs. During LCF tests, dwelling at maximum stress introduces creep damage into low cycle fatigue, then decreased LCF fatigue cycles. At LCF tests with constant maximum stress and varied minimun stress, fatigue/creep interaction curve exhibits a maximum fatigue life at certain stress condition and frac...             本文研究了缺口对GH33A合金在高温低周疲劳及劳疲/蠕变交互作用下的力学行为。结果表明:缺口使GH33A合金低周疲劳寿命缩短,其缩短的程度随缺口尖锐程度的增加而加剧。低周疲劳高应力时,保载时间的作用引入了蠕变分量,促使低周疲劳寿命Nf降低。在低周疲劳固定最大应力,改变最小应力而造成蠕变/疲劳交互作用情况下,其断裂寿命在一定条件下具有最大值,断裂机制可由纯疲劳断裂逐步转化为纯蠕变断裂,其程度主要决定于蠕变应力(或疲劳应力)分量所占比例的大小。 文摘来源   << 更多相关文摘         相关查询: 保载时间 保载载荷 载乌玛保 保 载 保载软化率 外载 保权 载波带 保肝 保元汤 保收率  对查询结果不满意
