Cyclic Behavior of Materials under Multiaxial Nonsymmertrical Loading
-
摘要: 在不同應變比下,按照總應變控制等幅循環階梯加載方式,測定了材料在拉-壓、拉-拉及扭轉循環下相應的循環載荷-變形曲線,得出了材料的循環應力及應力比隨應變比的變化關系。Abstract: Cyclic load-deformation curves of materials under tension-compression cycle and torsion cycle for different strain ratio were determined experimentally by using incremental step loading and total strain controlling technique in room temperature. Cyclic stress and stress ratio were obtained as functions of strain ratio.
