荷载历史 meaning in English
loading history
Examples
- It is concentrated on the investigation of the laws of damage initiation and development , under the conditions of monotone loading , cyclic loading , varies confinement pressures and triaxial equi - compression
主要是根据试验结果，对经历各种荷载历史后的损伤随荷载历史的发展演化规律进行了深入的研究。 - The combination of lateral stress and maximum vertical strain denotes the loading history and the reduction of tensile strength and compressive strength denotes the damage of concrete . this work is the theoretical foundation of study on the damage , of concrete due to loading history
分别用经历过荷载历史后混凝土试件的抗压和抗拉强度的劣化来定义其抗压和抗拉损伤，为下文深入研究损伤随荷载历史的发展演化规律奠定了扎实的理论基础。 - Sufficient test data were acquired for investigating the damage and constitutive behavior of concrete . second , according to the fitting of experimental data , the evolution equation of damage is obtained . the main factors affecting the damage development are examined and the causes are expounded
其次，通过对试验结果的非线性回归分析，得到损伤演化的经验表达式，并以此为依据，分别深入地研究了混凝土在经历过常规三轴受压和三向等压等荷载历史后，抗压强度和抗拉强度随荷载历史增加而发生劣化的演化规律。 - The aim of this dissertation is to shed some light on these subjects . first , systematic experimental study and theoretical analysis have been performed to study the damage of concrete due to loading history . in addition , an artificial neural network approach is developed to study the constitutive relations of materials , and some constitutive models of concrete under various loading history have been established
本文针对目前大坝设计和研究中混凝土材料损伤及本构特性这个薄弱环节，在深入分析国内外有关成果的基础上，从理论和试验两个方面对混凝土材料经历过荷载历史后的损伤特性进行了深入的研究；同时，将人工神经网络技术应用到混凝土本构领域，建立了一系列在各种加载形式下的混凝土材料模型。
