tensile stress-strain curve 中文意思是什麼
tensile stress-strain curve
解釋
拉伸應力應變曲線-
The first stage is primary slip then followed by secondary slip ; the last stage is due to dislocation passing the slips. the cyclic stress strain ( css ) curve exhibits a stronger hardening occurred in cyclic plastic deformation than that in tensile test
建立了拉伸和應變疲勞的有限元模型,使用基於晶體滑移模型的數值方法,對晶體內部滑移系的啟動以及滑移繫上的分解切應變、切應力這些無法試驗觀測的變量進行計算,分析它們對晶體塑性變形的不同影響。 -
Under the promise of the practical applica tion an frugality, we determined the formula of sfpc and the stud y range. according to principle of damage mechanics, we deduced one axis tensile - compressive stress - strain relations and numeral fitt ing results with the finite element method. with experiment curve and stress - strain curve, we prove theorization method is practical
根據損傷力學原理建立了材料單軸抗拉一抗壓本構模型,並應用有限元軟體對其進行了數值擬合,通過實驗曲線、本構模型曲線之間的關系,證明了理論推導方法的可行性。
