monotonic stress
解釋
單調重音-
Sm scales the nonlinear variation of tangential modulus during monotonic loadings into a piecewise linear distribution, which can easily be modified to simulate specific characteristics of soil material behavior during cyclic loadings. sm can simulate dynamic stress - strain response of arbitrary cyclic loadings
該模型將單調加載情況下呈非線性變化的切線模量量化成一種呈分段線性分佈的幾何結構，並通過對這種結構加以變換，來描述循環加載情況下材料的特性。 -
When we draw the stress - strain relation of monotonic tension and pure torsion at the same co - ordinate namely equivalent effective stress and equivalent effective strain co - ordinate, it is obviously that the equivalent effective stress - strain curve of monotonic tension and pure torsion are basicly superposition while the equivalent effective strain is smaller. but equivalent effective stress level of monotonic tension was higher a little than that of pure torsion
把a3鋼試件單一拉伸和純扭轉時應力應變關系繪于同一個坐標中即等效應力和等效應變坐標中，可以看出當等效應變較小時拉伸實驗得到的等效應力應變曲線與純扭轉實驗得到的等效應力應變曲線基本重合。但單一拉伸較純扭轉得到的等效應力要略高一些。 -
Test results show that : ( 1 ) the amount of creep deformation during monotonic primary loading depends on strain rate before creep, creep stress level, and creep time ; ( 2 ) during monotonic primary loading, the stiffness increasing magnificently shortly after creep ; ( 3 ) the direction of creep will change from positive creep ; to neutral creep and negative creep during unloading, while during reloading, it will change from negative, to neutral and positive creep
試驗結果表明： （ 1 ）在初始加載過程中，經過一定時間蠕變后黏土的強度有很大的提高； （ 2 ）在卸載過程中，隨應力值下降黏土的蠕變表現出由正蠕變、中性蠕變到負蠕變的逐漸轉化； （ 3 ）在重復加載過程中，隨應力值增加黏土的蠕變表現出由負蠕變、中性蠕變到正蠕變的逐漸轉化。 -
The alloys, which were cold - worked followed by recrystallization annealing, display cyclic softening in the range of low strain because the cyclic stress - strain curve lies below the monotonic stress - strain curve, and show cyclic hardening in the range of high strain because the cyclic stress - strain curve lies above the monotonic stress - strain curve
在低應變范圍，冷加工后經再結晶退火處理的錯合金的循環應力一應變曲線位於單調拉伸曲線的下方，表現為循環軟化;在高應變范圍則位於單調拉伸曲線的上方，表現為循環硬化。 -
Using the general finite element programming package of ansys10. 0, the study of gabled frames beam - column end - plate connections is made, considering synthetically nonlinear ( material, geometry and contact ), bolt pretension forces and ratio of axial compression stress to strength. elastic - plastic finite element analyses are carried out among 28 species of 3 series under monotonic loads, in order to discuss the influence of parameters including stiffness of end - plate, bolt diameter, friction coefficients and so on
本文使用通用有限元軟體ansys10 . 0綜合考慮了三重非線性（材料非線性、幾何非線性以及狀態非線性）的影響，同時考慮了螺栓預拉力的影響，對考慮端板厚度、端板加勁肋的設置、螺栓直徑、摩擦系數等參數不同的3個系列（端板系列，螺栓直徑系列，摩擦系數系列） 28個試件進行了有限元數值模擬，對連接節點的性能進行了分析研究。
