Abstract

The invention discloses a method, system and device for calibrating a deformation behavior of a material and a simulation platform, and the method comprises the steps: processing the material, and obtaining the test data of the material under different loading conditions; according to characteristics of the material and experimental conditions, carrying out deformation behavior simulation of the material, and constructing a finite element simulation model of the material; processing the obtained test data, and compiling an experiment and simulation error function; and based on the simulation platform, optimizing the experiment and simulation error function and the finite element simulation model, and obtaining an optimal simulation result. The simulation platform comprises a finite element simulation Simcode module, an MATLAB (matrix laboratory) error analysis module and an Optimization parameter optimization module. Based on the established simulation platform, simulation software is automatically operated to complete the process of simulation-optimization-parameter correction-re-simulation and re-optimization, and through multiple times of parameter optimization and finite element simulation calculation, a finite element simulation result is close to data obtained through experimental testing. And digitization and full automation of the whole material deformation mechanical behavior characterization process are realized.

Description

technical field [0001] The invention belongs to the field of algorithm optimization, and relates to a method, system, device and simulation platform for calibrating material deformation behavior. Background technique [0002] Materials are the hallmark of human technological progress. At present, various materials are applied in various forms in every industry, not only in people's daily necessities, such as cooking utensils, packaging materials, etc., but also in aerospace, national defense, automobiles, Industrial fields such as electronic communication.
