摘要: 对双相钢的变形模型进行了计算机仿真。为了采用DDSⅢ动态仿真语言设计仿真程序,在原数学模型中,引入了一个初值为零的伪常微分方程,也可采用取消源程序中与积分有关的部分语句的方法。前一种方法具有普遍意义。仿真结果表明:用马氏体体积分数对双相钢的均匀真应变作图可更好地反映双相钢中各组份相的性能对双相钢均匀真应变的影响。对一些文献中矛盾的结果进行了解释,提出了改善双相钢匀真应变的途径。

Abstract: A Computer Simulation of the deformation model of dual phase Steels has been performed. DDS Ⅲ (Digital Dynamics SimulatorⅢ) was used to program. In order to use DDS Ⅲthe technique used is to introduce a pseudo-ordinary-differential equation or delete some statements related to integration from the source program. The simulation results demonstrate that the curve of uniform true strain of dual phase steels vs martensite volume fraction in dual phase steels is better than curve of uniform true strain of dual phase steels vs strength of dual phase steels for showing effect of component phase properties of dual phase steels on uniform true strain of dual phase steels. The Contradictory results in references were explained and way of increasing uniform true strain of dual phase steels was suggested.
