step test中文什么意思
例句與用法
- Analysis on the age characteristics of step test indexes and its influential factors
臺階指數(shù)的年齡變化特征及影響因素 - Step standard test method for simultaneous thickness and electrode potential determination of individual layers in multilayer nickel deposit step test
多層鎳鍍層中單層的同步厚度和電極電勢測定的標準試驗方法 - So it is very important to understand the cyclic deformation behavior of zircaloy - 4 . in this paper , bauschinger effect of zircaloy - 4 with different metallurgical state at room temperature and 400 ? is investigated in an incremental step test and cyclic deformation test under constant strain control . bauschinger effect during cyclic deformation is described by using back stress , which is mainly responsible for bauschinger effect ; back stress is attained by using kwl " s method
本文采用單試樣逐級加載循環(huán)變形和恒應變幅循環(huán)變形試驗，研究了不同冶金狀態(tài)、溫度、氫以及固溶處理下的zr - 4合金的bauschinger效應現(xiàn)象；種種結果表明，影響bauschinger效應的主要因素是背應力；本文正是從背應力的角度來分析各種狀態(tài)下zr - 4合金的bauschinger效應現(xiàn)象；背應力的計算主要通過使用kwl方法而獲得。 - The experimental results is shown as followings : ( 1 ) the cyclic flow stress - strain curves in an incremental step test could be expressed as the power law relation : ( 2 ) when the strain amplitude is lower during cyclic deformation tests under constant strain control , softening firstly appears , then gradually hardens with the increasing numbers of cycle ; when the strain amplitude is higher , hardening firstly appears , then gradually softens
試驗結果表明： ( 1 )循環(huán)流變應力與應變的相互關系曲線均符合冪律關系式： ( 2 )在室溫下進行恒應變幅循環(huán)變形過程中，當所控制的應變幅較小時，該材料首先出現(xiàn)循環(huán)軟化，之后隨循環(huán)周次的增加直至循環(huán)失效前該材料出現(xiàn)了硬化現(xiàn)象。當應變幅較大時，該材料開始出現(xiàn)硬化，然后隨循環(huán)周次的增加才出現(xiàn)軟化。
