Description

Technical Field

[0001] This invention relates to the field of computer simulation technology, and in particular to a design method for a database architecture for simulating metallic materials. Background Technology

[0002] The design challenge of a metal materials simulation database architecture lies in the vast differences in material types and data requirements. This data can be categorized into thermophysical property data, fundamental data, material constitutive models, and more. From a holistic material classification and management perspective, we need to clarify the relationships between different material types, their corresponding temperature ranges, and data formats. Only by retaining this data can we meet the operational needs of simulation. Material property data is complex and specialized. Due to the anisotropy of some metals, exhibiting different properties in different directions, this adds an extra dimension to the architecture design. Furthermore, simulation data for metal materials typically needs to consider variations within a specific temperature range; for example, the elastic modulus changes with the forging temperature. Additionally, the simulation data for metal materials should encompass data generated throughout the entire development process, rather than just a portion of the simulation data. Therefore, the database architecture design must consider the integration of material types and processes. Summary of the Invention

[0003] The purpose of this invention is to address the problems existing in the background art. This invention proposes a design method for a metal material simulation database architecture. This architecture design method considers aspects such as simulation software, material types, and simulation processes, mainly including five categories of metal materials: bars, plates, wires, strips, and tubes. By classifying materials according to their types, processes, and data requirements, the method enables the management and querying of simulation data.

[0004] This invention provides a method for designing a database architecture for metal material simulation. It categorizes and organizes common metal materials, and then designs the structure of the data attributes for each material type. Its key features are: (1) Preliminary classification of metallic materials, including: material type and material grade. Among them, material type includes bars, plates, wires, strips and tubes; (2) Classify the different simulation processes involved in each material type, including forging, heat treatment, welding, etc.; (3) Each classification structure is composed of different underlying data and special requirements according to different product needs, but the data description structure type remains consistent. The underlying data is classified according to thermophysical parameters (Young's modulus, Poisson's ratio, density, mechanical properties), basic information (chemical composition), and constitutive equation. (4) Describe the thermophysical parameters in the underlying data by data name, unit, temperature, and special requirements; (5) The basic information in the underlying data is described by chemical elements, element content, and remarks; (6) The constitutive equations in the underlying data are described by parameters such as equation variables and equation constants; (7) Preferably, mechanical processing simulation is divided into two categories: shot peening and pipe machining; (8) Preferably, welding simulation is divided into six categories: brazing, friction welding, diffusion welding, electron beam welding, argon arc welding and laser welding.

[0005] Advantages of this invention: This invention proposes a design method for a metal material simulation database architecture, which has the following beneficial effects: This design method first divides materials into five categories: bars, plates, wires, strips, and tubes. Each category of materials is described according to simulation processes such as forging, heat treatment, machining, and welding. Each simulation process has dozens of different performance items, and each performance item is defined according to different material data categories. Then, this data structure design is described using a database design language. Based on this metal material simulation database architecture design, the simulation performance data of metal materials can be completely expressed. Attached Figure Description

A preliminary classification of metallic materials is performed, including: material type and material grade; The simulation processes involved in each material type are classified, including forging, heat treatment, welding, etc. Each classification structure consists of different underlying data and special requirements based on different product needs, but the data description structure type remains consistent.
