Development of Generalized Computer Program for Thermo-mechanical Simulation incorporating Phase Transformation and Establishment of Database

包含相变的过程，如固中组织变化和熔化/凝固区域，通常是复杂的现象，其中金属组织。温度和应力/应变是相互影响的。代表性研究人员及其同事将这种现象称为金属-热-力耦合，并提出了基于金属-热-力的基本理论。开发了几种材料的热力学性能数据库和一些有限元计算机程序，用于热处理、焊接、铸造和连铸等工程过程的模拟，并通过实验验证了其有效性。许多行业和研究机构都要求我们使用由此开发的计算机代码。本项目的主要目的之一是开发初学者易于使用的计算机代码；结合几种材料和边界条件数据库，构建了热处理仿真程序“HEARTS”。进一步的研究活动是如何将“HEARTS”应用于铸造和焊接工艺，以及收集材料和边界条件的数据

The processes incorporating phase transformation such as in-solid structural change and melting/ solidification area generally complicated phenomena in which metallic structures. temperature and stress/strain are affected each other. The representative researcher and his coworkers termed the phenomena as metallo-thermo-mechanical coupling, and the fundamental theories based on the metallo-thermo-mechanics. database of thermo-mechanical properties of several materials and some finite element computer programs have been developed for the simulation of engineering processes such as heat treatment, welding, casting and continuous casting, the validity of which are also confirmed by experiments. A lot of industries as well as research institutes have asked us to utilize the computer codes thus developed.One of the main purpose of this project is to develep the computer codes easily used by beginners ; heat treatment simulation program "HEARTS" is constructed being combined with database of several kind of materials and boundary conditions. Further research activities are mode to apply the "HEARTS" to casting and welding processes, and to collect data of materials and boundary conditions
