摘要
在非线性分析中,应力-应变关系不但与当前的应力状态有关,还与其应力历史有关.计算过程中需要对应力历史进行存储.作者采用面向对象的编程方法,根据材料当前的应力状态,实现了智能化地存储应力历史.从而克服了面向过程的结构化程序设计方法的不足,节省了空间,降低了编程难度.作者结合三维实体单元模型,介绍如何对其进行面向对象的非线性有限元程序设计.
In the nonlinear analysis, stress state and stress history are in respect to stress-strain law. It is needed to store its stress history in calculation and analysis. Based on stress state of material, Object-Oriented Programming method used has the advantage in storing stress history intelligently. It overcomes the shortcoming of Process-Oriented Programming method, saves space and reduces difficulty of programming. Based on the three-dimension solid element, how to design for Object-Oriented nonlinear FEM Program.
