ABAQUS crack propagation data extraction method and system and computer readable storage medium

Abstract

The invention discloses an ABAQUS crack propagation data extraction method and system, and a computer readable storage medium, and belongs to the field of data extraction. The ABAQUS crack propagationdata extraction method comprises the steps: generating and outputting a first function template through determining to-be-extracted data information; receiving an instruction for modifying the file format of the first function template, and converting the first function template into a second function template; extracting a field variable value and a data matrix of unit and node number information in the second function template, wherein the unit and node number information is specifically node numbers and node and node coordinate information corresponding to units; and processing the fracture unit data, and establishing a data extraction function library so as to complete the extraction of the crack propagation data. The ABAQUS crack propagation data extraction method is simple in operation, can achieve the quick and automatic extraction of the ABAQUS crack propagation data, and can greatly improve the extraction efficiency of the ABAQUS crack propagation related data.

Description

technical field [0001] The invention relates to the field of data extraction, in particular to an ABAQUS crack extension data extraction method, system and computer-readable storage medium. Background technique [0002] In the field of traditional numerical simulation, the crack propagation area of ​​rock, metal and other materials is generally simulated through phase field simulation and damage constitutive model based on the idea of ​​continuum mechanics, which cannot truly reproduce the two-dimensional or three-dimensional shape of the cracking direction and cracking position. feature. In practical work and research, most of the calculation and simulation methods of fracture propagation such as finite discrete element method and block discrete element are used. Taking the COHESIVE unit of the finite discrete element method implemented by ABAQUS as an example, this unit realizes the crack propagation by defining the elastic constitutive model and the fracture failure mode...

Problems solved by technology

[0003] However, the current version of ABAQUS numerical simulation software does not have the data extraction function of the fractured unit. Therefore, it is necessary to do some secondary development of the ABAQUS software in order to obtain the total length of the fractured unit and the time-dependent Changes in the total area of ​​the fractured elements and the change of the total volume of the fractured elements over time

Generally, it is developed through PYTHON scripts. This development method requires a high language foundation and a deep understanding of the relationship between PYTHON and ABAQUS module calls, which is not conducive to some researchers and engineering simulation personnel who do not have these conditions.
