摘要
人类工业文明发展至今,石油化工、核电、航天航空等领域取得了显著的技术进步。在实际服役过程中,诸多复杂关重机械装备往往承受室温或高温循环载荷的作用。因此,对关重装备构件进行结构完整性评估,发展适用而精确的循环本构模型是其中必须且关键的一环。回顾和总结宏观唯象循环本构模型、细观循环本构模型和晶体塑性循环本构模型的发展历史和最新研究进展,针对各类模型的有限元实现方法和结构应用进展进行综述,总结和比较了各种模型在工程应用的优势和不足,并对未来的发展趋势进行展望。
With the development of human industrial civilization, remarkable technological progress has been made in the fields of petrochemical, nuclear power, aerospace and aviation industries. In the actual service process, a lot of complex and key equipment is often subjected to cyclic loadings at room temperature or high temperature. Therefore, for the structural integrity assessment of key components, the development of robust and accurate cyclic constitutive model is quite necessary and critical. In this work, the development history and latest research progress of macro-phenomenological cyclic constitutive models, meso-cyclic constitutive models and crystal plastic cyclic constitutive models are reviewed and summarized. Furthermore, the finite element implementation method and application of various models are reviewed, while their advantages and disadvantages are also summarized. The development trend of the cyclic constitutive models in the future is also prospected.
